I so appreciate that you're taking the time to demonstrate the laws of motion in such a visually intuitive way, my son will love it. A pity there's no way to demonstrate F = G M1 M2 / r^2 - or if there is I can't think of it. Maybe you could show Galileo's Principle of Relativity. It's the basis of the laws of motion after all.

[@andrewyek]

do you have newton 3rd law applied in vacuum ?? thx andrew

[@willoughbykrenzteinburg]

Yes. A vacuum is just the absence of a medium - like air. It's not the absence of the laws of physics.

[@TomokosEnterprize]

Neat !

[@jlfqam]

Impressive demonstration. Let me please add a comment: Newton's third law only applies when Mark Vande Hei applies a force against a body or object that does not move for example the a wall of the space station, then F(wall)=-F(Mark). However when Mark pushes the basketball F(ball)

[@alleny178]

You are confusing this with acceleration. It is true that |a(ball)| >> |a(Mark)|, but F(ball) = F(Mark). Since the mass of Mark is larger, it is just simple algebra to see why the acceleration of Mark is smaller than the ball.

[@JamesCharbonneau]

@@alleny178 The original post is not correct. Allan makes a very important point about distinguishing force and acceleration here. In the original comment F(Joe)=-F(Mark) are statements about forces acting of different objects, so they don't cancel out. The net force on Joe is the force from Mark. The net force on Mark is the force from Joe. Those forces cause each of them to accelerate. Another way to approach this is from conservation of momentum. Before the push both Joe and Mark and stationary (in the frame of the space ship). We can say that their total momentum is zero. When they gets pushed, each of them moves in opposite directions, and because momentum is directional (a vector) their total momentum is still zero. However, if we simply look at the momentum of Joe, it started as zero and is now non-zero. The change in momentum is due to the net force from Mark. Newton's second law is the the net force on an object is equal to the change in momentum of that object with respect to time F_net = dp/dt.

[@jlfqam]

@@alleny178 accelerations are proportional to forces. The point is that reaction force is limited. When a vehicle crosses over a bridge the reaction force (or resistance of the structure) will hold, but a heavier vehicle will exert a force on the bridge that will overcome the resistance force, at that very moment F(resistance)

I realy want to be an astronaut. Realy this is not just talk but no one supports me.For real you are lucky

[@a.d7656]

Dig Bick Wow You really supported me with your words. I do everything you say. But some of my family and my community they destroy me. There are no museums or centers support anyone who wants to become an astronaut. This is really sad.

[@DoctorZisIN]

I feel for you, I know it doesn't seem fair that some people have so many advantages to become something like an astronaut. A step toward being an astronaut would be becoming a pilot. Is that a possible goal for you? Could you find a way to learn to pilot airplanes? In some countries you can volunteer for the military and they will teach you to fly if you show interest and aptitude for it.

WHY AND HOW DREAM EXPERIENCE AND PHILOSOPHY ULTIMATELY MADE THE TRUE UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE POSSIBLE: Consider what is THE SUN, and then consider what is THE PHOTON (c, A POINT). THINK about F=ma AND E=mc2. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND ACTUAL IN BALANCE. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It is a very great truth/fact that the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THINK about it. THOUGHTS ARE INVISIBLE. Now, very THOROUGHLY consider what is THE EARTH. It is ALSO a very great truth/fact that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. THE EYE IS THE BODY. The BALANCE of being AND EXPERIENCE is ESSENTIAL. (BALANCE AND completeness go hand in hand.) THINK about it. Very carefully consider what is THE EYE. Notice the black space of THE EYE, AND notice that THE DOME of a person's EYE is ALSO VISIBLE. MAGNIFICENT. The stars AND PLANETS are POINTS in the night sky. NOW, we OVERLAY what is THE EYE in RELATION to what is THE EARTH. (Very importantly, outer "space" involves full inertia; AND it is FULLY INVISIBLE AND black.) SO, we now consider the semi-spherical, translucent, AND QUANTUM GRAVITATIONAL DOME that is the BLUE SKY. (It is a BALANCED reflection, as defined.) We can LOOK at what is then THE BLUE EARTH. It ALL makes perfect sense. Points are POINTS. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great. The ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Dream experience is possible/potential AND ACTUAL IN BALANCE. There is no outsmarting the GENIUS OF DREAMS. Now, dream experience is/involves true/real QUANTUM GRAVITY; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Dream experience GROWS/INCREASES. Dreams BALANCE being AND EXPERIENCE. THE EYE is ALSO THE BODY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, BALANCE AND COMPLETENESS go hand in hand. ELECTROMAGNETISM/ENERGY IS GRAVITY. IT IS DEFINITIVELY AND CLEARLY PROVEN. It ALL makes perfect sense. SO, the INTEGRATED EXTENSIVENESS of thought (AND description) IS improved in the TRULY SUPERIOR mind. Absolutely ingenious !!!!!!! Dreams make thought MORE LIKE sensory experience in general, thereby IMPROVING upon memory AND UNDERSTANDING !!! Learn to think for yourselves. Very carefully consider the man who is standing on the EARTH/GROUND. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Piece it ALL together. Fantastic !!!! So, THE EYE is, in fact, a BALANCED WHOLE in RELATION to (AND WITH) the SPACE around it. THE EYE is ALSO the body. The BALANCE of being AND EXPERIENCE is ESSENTIAL. BALANCE AND COMPLETENESS go hand in hand. We can see that these spaces are, in fact, proportionately advanced IN BALANCE. SO, it is now time to turn to the DIRECT AND FULL COMPARISON of what is THE SETTING MOON AND THE ORANGE SUN. The fully illuminated AND setting MOON MATCHES the brightness of the SETTING AND ORANGE SUN. MOREOVER, the curvature or shape of this Moon MATCHES that of the EARTH/ground. Also, this Moon AND Sun are the SAME SIZE as what is THE EYE (of necessity). Notice that these manifestations or forms occur at EYE LEVEL/BODY HEIGHT. Therefore, these are QUANTUM GRAVITATIONAL incarnations or forms that must be identical (on BALANCE) to what is the EARTH/GROUND AND LAVA. The COMPOSITION of lunar rocks IS practically IDENTICAL to that of Earth rocks. SO, the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE) is a BALANCED, QUANTUM GRAVITATIONAL, AND BODILY/VISUAL EXPERIENCE in RELATION to what is THE EYE, THE EARTH/GROUND, AND LAVA. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The Moon may also be blue. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/AS F=ma, E=mc2, AND WHAT IS PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, the rotation of the Moon MATCHES it's revolution. It is PROVEN. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. IT ALL MAKES PERFECT SENSE. THIS IS THE TRUE AND THE CLEAR UNIFICATION AND BALANCING OF PHYSICS/PHYSICAL EXPERIENCE. BALANCE AND COMPLETENESS go hand in hand. Really THINK about it ALL. GREAT !!!!

If you think rockets can work in space, then you do not understand Newton’s 3rd law at all...

[@willoughbykrenzteinburg]

Not the case. However, rockets can be better explained using the conservation of momentum - a close cousin of Newton's third law. This law states that the momentum of any arbitrary system will be the same. It's absurdly simple. The rocket containing its fuel is our system. All the matter that makes up that system will have the same momentum - always. So, when that rocket ejects mass away from it (in the form of fuel) at a very high rate of velocity, that ejected mass now has very large momentum. However, our entire system's momentum must be conserved, so to compensate, the rocket and remaining fuel must necessarily be propelled in the opposite direction to counter the momentum of the ejected fuel. If you want to apply Newton's laws, the pressure inside the rocket exerts a force on the fuel/mass, and the mass itself counters with an equal and opposite force back onto the rocket.

[@peterford5408]

LOL Sometimes I wish I knew whether people like you really believe all these conspiracy theories, or whether you're just trolling. You know you can see the ISS for yourself, right? It's visible with the naked eye in certain circumstances. You just need to know when to go outside for a viewing, and where in the sky to look. NASA's 'Spot the Station' website will tell you. But of course, if you really do believe the crazy theories, it's not due lack of counter-evidence. There are underlying problems of epistemology and probably psychology at play.
