What is Acceleration In Physics?

This physics video tutorial provides a basic introduction into acceleration. It explains how acceleration relates to a change in speed or direction which is equivalent to a change in velocity.

Can I ask what motivates you to make these videos specially the 2 hour long chemistry ones? It’s really impressive. I appreciate people like you who take the time out of their day to teach others.

Acceleration is the rate of change of velocity. Usually,  acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

omg thank youuu so much, not even a minute into the video and i was able to understand something our teacher was unable to do in a whole semester

Speed + Direction = Speerection
Kidding asside you help out a lot man.

I love you man thanks for all you do for us

You are life saver!! I really appreciate you.

Please make videos on langrangian and Hamiltonian mechanics. Thanks

Here is an idea: I think both space and velocity DO NOT EXIST because both depend on an absolute and arbitrary frame of reference that do not exist.

On the other hand, acceleration can be measured absolutely, independent of any frame of reference.
So acceleration exists, but not space or velocity.

So we need a NEW theory of Physics, in which only acceleration exists, but not space or velocity.

For example, it is possible to measure the acceleration of a spaceship independent of any frame of reference.
But it is impossible to measure the position or velocity of the spaceship if you don't have a frame of reference. A frame of reference is always RELATIVE to some arbitrary object in the universe. An absolute frame of reference does not exist. Since an absolute frame of reference does not exist, neither do position or velocity.
So both position or velocity need to be purged from Physics.
