Why is the parachutist always falling downwards even though the acceleration is upwards when he opens the parachute and when he reaches constant velocity

[@bscorazon]

but wouldnt the weight increase as velocity increases, since acceleration also is increasing?

[@heghog-xz4uo]

3:41 "As the person's velocity increases though" Why does it increase in the first place? If there is not an extra force other than the weight, why would velocity increase?

[@brutalbomber3721]

U sure ur not sleeping whilst watching this

[@jasmeennasir9568]

It’s because of gravitational energy weight

[@Anananana12345]

Why does a object automatically gain 10 m/s square when falls ?

[@zulfanrizky8601]

Gravity my dear

[@FarhanKhan-ye2ve]

How do you make these videos ? They’re awesome !

[@arian6565]

wait, does that mean in a vacuum, we will accelerate infinitely till 99,99999% and so on light speed? assuming you would somehow have infinite space to fall? Im not an expert so pls don't blame me if that's a stupid question

[@ssjbevegeta3008]

Well , that can only happen near a black hole where gravity would be monstrous enough to pull you in at light speed , other than that if you are falling in a vacuum on a planet , no matter how far you are you will fall at a constant acceleration depending on the planets or celestial body now if there is infinite displacement to fall through with constant gravitational acceleration, then you can say that you'll surpass the velocity of light (assuming you dont get affected by either the time or speed ) , it'll take a rounded off year to reach that velocity with earth's gravitational constant and take about approximately 4.5 quadrillion metres to fall through. As in a vacuum with no celestial body , you wouldn't move anywhere since you're not affect by a force.

[@gunnu9855]

Hi sir, i don’t understand why the terminal velocity would be lower with the parachute

[@urthoperator3126]

Due to air resistance. Higher area with the parachute, more particles impeding you to accelerate, or decelerating you if you had a higher terminal velocity.

[@willoughbykrenzteinburg]

Drag is a complex thing - there are many factors that go into it. Two of those factors are something known as the drag coefficient and surface area. The higher the coefficient, the higher the drag. The higher the surface area, the higher the drag. When you open a parachute, you increase both of these greatly - which greatly increases the force of drag. The other factor that affects drag is speed through the air - the faster the speed, the higher the force of drag. Terminal velocity is reached when the upward force of drag is equal to gravity, so before you open your parachute, you get faster and faster and drag gets higher and higher. Gravity stays the same and eventually the drag reaches the same as gravity and you stop accelerating. Then you open the parachute and suddenly drag is WAY higher than gravity, so you have to slow down for the drag to come back down to meet gravity and reach this new - lower - terminal velocity.

[@Hello-fv6oe]

Great video. What do we do when they ask this? Describe the motion of objects falling in a uniform gravitational field with and without air/liquid resistance (including reference to terminal velocity) Thank you 😊

[@olive4789]

With air/liquid resistance, terminal velocity takes place. - As explained in the video, the resultant force increases due to gravity, weight etc. But, acting against this is collisions with the air/liquid (air/liquid resistance) which also increase due to the velocity increase, causing a decreasing acceleration. Until, they each cancel out and terminal velocity is reached. However, when there is not air/liquid resistance the resultant force will not have any opposing forces so will continue to accelerate until stopped. so the motion of objects with resistance slows down whereas lack of resistance means that it continues to accelerate until gravity no longer acts on the object (e.g. it hits the floor) im not sure how well I explained that but I hope it helps

[@Hello-fv6oe]

@@olive4789 heyyy thank youuuuu and good luck on any future exams☺️☺️

[@tokyo7671]

will the speed of the object increase once its terminal velocity is reached?

[@kyawzsilta1258]

No it wont

[@willoughbykrenzteinburg]

No - that's why they call it *_terminal_* velocity.

[@ameliesymmons]

Velocity is just speed over a given time, so technically they are the same thing. So once it’s reached it’s terminal velocity, it’s technically reached a constant speed.
