1. How is acceleration different from velocity?

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Whereas, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

-Here is a formula for acceleration.

-And due note there are multiple types of velocity, namely starting and final velocity there are multiple formulas. I urge you to learn them!
