The velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time.
The condition in which a body covers equal distance in an equal interval of the time is known to be uniform velocity. In equation( d=v t ) v is the average velocity of a body during time t. if both its magnitude and direction do not change with time then it can be said that the body is at uniform velocity. The rotation of the moon around the earth is an example of uniform motion.
Acceleration is defined as the rate of change of velocity and is an example of a vector quantity
Uniform acceleration: When an object is travelling in a straight line with an increase in velocity at equal intervals of time, then the object is said to be in uniform acceleration. Free falling of an object is an example of uniform acceleration.
