Physics - What Is a Centripetal Force?

This physics video tutorial provides a basic introduction into the centripetal force which is a center seeking force that keeps an object moving in uniform circular motion. The centripetal force is created by other forces such as tension, static friction, and the gravitational force just to name a few.

I never even heard of the word “centripetal”. I always wondered how a train was able to stay on its tracks, and this word popped up. I’m 56 years old, and I’m trying to catch up on things 😆. I dropped out of high school, but thankfully I was still able to find a decent job and raise a family. Thank you for explaining centripetal force. I look forward to following you and learning more!

[Nickelicious]

The statement that its not a force in and of itself but cause by other forces was the “ah-hah” moment for me, thank you!

Ive passed 4 upper level physics and chemistry classes thanks to your videos. Please never stop doing this

[thinklikebaeeliza]

Man, I thought you were the organic chemistry teacher. I’m so glad I’m learning this through you.

Fugitive is an English word that is used for a person who is running away from the law. CentriFUGAL force tries to pull the string away from the centre - like running away.

You have to pull an object towards centre when it is trying to move away to keep it rotating.

For eg: Gravity pulls the earth towards the centre.😊

It's functions like integral of arcsinh (x) etc

[innocentntuli]

I'm having trouble finding* videos relating to hyperbolic functions for integration.

[JohnDoe]

Why wouldn't it be kinetic friction?

[alchemy]

Can you apply centripetal force to a stationary object? Or then it would just be called regular force or just force?

[adrianahernandezj]

thank you for coming through time and time again <3

[vashthestampede]

OMG YOUR EXPLANATIONS ARE GODLY! great video!

[tukhtamishchoriev]

Assalom aleykum.(Good eveniing )Thanks for these useful videos .Actully these are the perfect lessons to learn, thanks again.Please carryo on your job

[jamesmatheson]

The purpose of centripetal force is a ring moves a ball and the center has less gravity then the ball And you can control the gravity in the center
And if the center moves too fast you add another ring and ball and increase the gravity of the outer ring and the center gravity stays constant by making the first ring and ball have more force

Appreciate you brother, I have a physics exam tomorrow and i think this will come in clutch

[wallflwer]

Any new GRE videos are coming soon ? Thanks 😊

[frownyclowny]

Studying for my physics final, you're a big help with this :)))

[danieldutakolmarialdit]

I seconded this teaching walai
I can't wait to see more on this platform

Can you please the difference between Centripetal Force and Angular Velocity/Momentum? Really confuse with what the difference is what to use what!!!

[gooddeedsleadto]

This is what I think about? Is it correct.

Centrifugal force in circular motion is comparable to the the reaction force in linear motion on the driver when he applies the brakes?

The forces applied on the car to stop is the braking forces exerted in the backward direction.

The force that throws u in the forward direction after braking is your body’s reaction.

Braking force is comparable to the inward pull it tension i the spinning string and if the string loses its strength the cutoff portion would feel the centrifugal force and would be thrown away radially out.

If a stone is attached to a spinning string or rope the stone would go tangentially out due to the tangential or instantaneous velocity.

Radially Inward acceleration always exists because the velocity is continuously changing.
The radially inward leads to radially inward force which is newtons second law of motion.

Centrifugal force is the mass of the rock times the inward acceleration. It is a fictitious force. The real force is centripetal force.

Where as the centripetal force proportional to square of the velocity and inversely proportional to the radius.

Im still in 8th grade still dont know y im here guess i like your teaching 😀😀😛😛👍
