Free Fall with Air Resistance - Terminal Velocity (video 1 of 2)

Sir what is b

but the force is proportional to v squared not v

Only thing i dont understand is when you "factored" v

I didn't understand how you were supposed to integrate with an initial velocity

Mad lad

I appreciate the attempt to explain but without going step by step you just lose momentum. None of this really makes sense once you reach the integrals

Great video. Really enjoyed it.

please can u tell me how the rule becomes if the body is cube not sphere.. i really need help

Hello my question is this,
Taking the air resistance into account,the acceleration of a free falling body can be described approximately by a(v)=g-av^2.
Here g is the gravity acceleration and a a constant.
Determine the velocity v(t) of the body that is released from rest.

Thank you!

What if the body is a bubble under the water, 10 meters deep, for example. How will speed and acceleration be calculated, given that the size of the bubble will change and grow in each moment?

Great explanation. Simple but accurate. I have one question. Suppose we don't drop the ball but propel it through the air with a certain acceleration. Can we substitute g with this new acceleration and get the same results? Also, does this mean that the terminal velocity depends on the acceleration? So, with greater acceleration we can achieve greater terminal velocity? Thanks.

How can I find a value for b. I am dropping a basketball from different heights for my experiment and I don’t know how to find a value for b

(ooooomagod I'm gonna die)
Prof cancelled this class due to tech issues, and we still have a test on it and the previous chptr in 3 days.
🙄😳 wtf..... is happening.

This video was super helpful! Thanks a lot

Can someone please explain or tell me where to learn from that how e^(-bt/m) became 1-(bt/m) in short time limit?

As soon as I heard physics. Inja I subscribed nice job.

thanks what is time formula?

Very useful. Thank you!

Sorry but what if the body is moving down at t=0 ? Let's say at t=0, my v=8. How do I find out what is my v at t=10 ?

How can I find out the approximated time in which Vt will be reached?

The calculus manipulations were too complex for me, but the conclusion at the end of each calculation (initial, terminal, short term velocity situations) made sense with the calculation results. Perhaps you could create an appendix that puts in more steps so that those of us that like to play with numbers can have a chance of understanding the manipulations, even a little more. Thanks.

what does b stands for

What is b

What would be the time of flight

I think you tried to simplify the calculus parts, but it made it more confusing to someone that has gone through calculus.

How would you determine a value for b? I’m doing an experiment where I have to find g from the free fall of steel balls but I also have to factor in drag and I have no idea how to determine the constant.

Im here to understand what d and k stand for but here i got introduce to b. I feel like i wont able to grasp it if i dont understand what each variable stand for

Really appreciate these videos, thanks man!

Thank you

i don’t understand the calculus part cause we haven’t taken calculus yet but i understand the concept, it’s frustrating
