What Is Free Fall? | Physics in Motion

We head to a football stadium to explain freefall as we work through an example problem finding the maximum height of a thrown object.

As a physics teacher and adjunct professor for the past 15 years, I have to give the PiM team credit for producing an absolutely wonderful set of physics lessons that clearly deliver concepts and problems solving strategies to first time physics students. Thank you people of Georgia Public Television, for your vision to give PiM the green light especially at a time when remote or hybrid learning has become mainstreamed.

Great video! Concise and to the point, with excellent illustrations of the concepts. I will use it to help my HS students study these concepts.

You are a legend practical sir
Salute to you man ❤️

[PrathinavRaghavendar]

The proper defn helped me in my exam..thank you so much

[sunitashokeen]

Thank you so much sir your video helped me so much in my exams 😊😊

Just a quick tip!
Why is a ball thrown upwards considered free falling even though our hand exerted a force upon it?
When you let go of the ball, you are not exerting a force upon it anymore. The velocity of the ball would stay the same and continue to space if there were no forces acting upon it (inc gravity). The velocity of the ball changes because gravity becomes the sole force acting upon it and the ball is now free falling. The ball does not 'carry the force' or anything. The ball has a positive (non zero) velocity at first when it is moving upwards due to the force that had been on the ball but there is no force acting on the ball anymore.

Thanku very much... Cleared my doubts very easily and got some extra knowledge to add with!!

[abaanaasif]

Absolutely wonderful explanation of the concept!!!!

[sr-dlgu]

You said that gravity is the only force the ball was under on the way up. What about the force you gave it when you threw it up into the air?

Excellent video, very good illustration and examples!

Wait so you are saying, If I were to drop an anvil and a feather at the same time, let's say were were on top of a 50 foot building. They would land at the same time?
Nevermind, I realized a feather would have air resistance.

sir please answer how much gravitatioal field strength act on watermelons

[neerchettri]

Thank so much sir I want be connected with you

[yolandapradivadinatriprame]

Can you give me link of youtube that explain air resistance in free fall motion? Thank you

[roggaming]

It is very useful ☺️ ( no words to say 👏👏👏👏👏👏👏👏👏👏)

A ball is thrown straight up in the air: At the peak of its ascent, what is it doing? would it be falling down or instantaneously at rest??

[billie]

I find practicalli visual examples very helpful ...tt way i am fulli convinced tt thre was no sci-fi. .lol #thanx

[HNH]

How could a ball throwing up be only under gravity...How could a bullet firing upward be in free fall state? Its a misconception!!

[arthurrichard]

How about the watermelon and a baloon?

[detectiveconan]

constant acceleration and downward movement = free fall
