What is the difference between velocity and acceleration?

a.
velocity describes an object's position and acceleration describes how fast it moves.
b.
velocity is how fast an object moves and acceleration is the rate of change in velocity.
c.
velocity is used to determine the magnitude of force acting on an object, and acceleration isn't.
d.
velocity is a time-dependent property of an object, while acceleration is not.

Anwer: option B.Velocity is how fast an object moves and acceleration is the rate of change in velocity.

As you know velocity is the change is position divided by time, which is a measure of how fast something is moving. Now acceleration is the change in velocity divided by time which is how fast the velocity changes, this is its rate of change.

Both are rate of changes: velocity is the rate of change of position, and acceleration is the rate of change of velocity.
