Physics, Kinematics (1 of 12) What is Free Fall? An Explanation

[@watermelonvoid2909]

This actually very helpful, bro you are amazing and I came to this video to be disappointed but WOW please keep this content up and help more people in the future man, thanks again

[@stepbystepscience]

Thanks for taking the time to write such nice comment. It means a lot to me.

[@jameswilson6793]

life saver dude. Professors will teach the math parts like its science and just move on to the next slide. I appreciate this explanation.

[@stepbystepscience]

You are very welcome, I find a good complete introduction is helpful when beginning a new topic.

[@remybeans6346]

Wow! As someone who is struggling with physics, I went ahead to relearn the prior chapters using your videos and you made it so easy to understand!! I'm so grateful for your video, thank you for your work! I'm finally able to asking a question without googling how to do it.

[@stepbystepscience]

Glad I could help! Thanks for the positive feedback.

[@rockopaws1610]

When a 10 minute KZbin video taught me more than my teacher in two weeks

[@stepbystepscience]

Wow, thanks for watching and commenting.

[@doriangreg1601]

Brian Swarthout Thanks. :) I also left this comment on your website: Can you do videos on Kinematic Graphs? I'm learning that right now in AP MYB IB Physics at Suncoast High School. I just need clarification on interpreting the graph like at which point is the rest point, which point has the velocity 0, etc.

[@stepbystepscience]

I have videos on motion graphs. You can see a listing of all my videos at my website, www.stepbystepscience.com Here is a link to the first one....kzbin.info/www/bejne/anuQnoiboJKtfdk

[@alhazaranwar6276]

Step-by-Step Science please help me with this this is different it has speed before it drops what should I do then? A student measures the time required for a ball to roll across 0.5m of the lab table to be 0.4 second the height of the table is 1meter how far does it goes from the table? Please help me

[@stepbystepscience]

I have a vide0 for this two dimensional motion problem. You would just have to figure out the initial velocity, distance / time or 0.5 m/0.4 seconds. kzbin.info/www/bejne/a6Cvp5WAbJZ8aMU Does that help?

[@hodaashraf6234]

Before i watched this video i was totally hopeless l was even crying. Not because this concept in particular, but i just felt really overwhelmed because of my exams and when i struggled with this concept i just exploded and started crying. I watched many long videos and i didn't understand. But a 10 minutes video helped me and cheered me up. It may seem redecolus but i really needed to feel that at least something is easier than i thought ..

[@stepbystepscience]

I'm very happy to hear that this video helped you to learn. Best wishes to you.

[@littepoison]

∆Y= 1/2 at² become t= √2∆Y/a Because we are solving for time, how did we come up t=√2∆Y/a in ∆Y=1/2 at² ??? Multiply both sides by 2 Therefore, 2(∆Y)= 2( 1/2 at²) 2∆Y= at² Divide both sides by "a" 2∆Y/a = at²/a 2∆Y/a= t² Square root both sides √t²= √2∆Y/a t= √2∆Y/a

*Does the moon have any effect onto the free fall of an object between the moon and the earth, or the free fall of an object from the left side of the earth while the moon is on the right side of the earth?* I watched some videos explaining free fall on earth without the gravity of the moon which has effects on the oceans to cause low and high tides on earth.

[@stepbystepscience]

Anything that a regular person would drop onto the surface of Earth would not be effected by the moon's gravitational pull. The mass of the object would be too small and the distance would be too great.

[@willoughbykrenzteinburg]

The moon would have no noticeable effect on something free falling near Earth. The Earth's gravity would dwarf any effect of the moon's gravity. Things like tides are indeed caused from lunar gravity, but not really directly. Because the Earth is so large, there is a real difference between the parts of Earth closest to the moon and those parts farthest away, and this difference manifests itself through rising and lowering tides. This is very large scale stuff that doesn't have any effect on some regular object falling here on Earth.

Sir, I want to ask a question that Why sky diving (without parachute)is considered as Free fall, I get confused as there is air resistance in this... I am struggling a lot.... For it.. Please answer..

[@stepbystepscience]

Free fall is when something falls (or is moving upwards) and only experiences the force of gravity. We ignore all other forces, even though they may actually be there. Sky diving may not be the best example of free fall, but if we ignore air friction....

The acceleration is not a constant it is a variable. Things dont always freefall at a constant rate of 9.81 m/s2 but everything falls in the state of constant acceleration.

[@stepbystepscience]

This video is about free fall and when we talk about free fall we mean that the only force acting on the object is the force of gravity. And therefore it accelerates at a constant rate of 9.81 m/s2. Thank you.

[@dragonz_eye]

@stepbystepscience The comment is for those that think gravity on earth is always and only 9.81 m/s2. It's not. It is an independent variable. Even gravimeters can measure different rates of acceleration in the same spot within different variable. So,.. freefall is not always precisely g=9.81 m/s2. It's just a chosen rate. Thanks for clarification.
