Acceleration is a vector quantity that refers to the rate of change in speed or velocity of an object.

• TRUE

• FALSE

Velocity is the rate of change in displacement in a unit of time.

• TRUE

• FALSE

Acceleration is a vector quantity that measures displacement over the change in time.

• TRUE

• FALSE

If an object covers equal distance at equal intervals of time then it is moving at constant speed and still not accelerating.
