Explain the term acceleration.

MotionThe motion of an object is defined by two parameters. An object is said to be in motion when its position from a reference point (displacement) changes with time Uniform MotionThe motion of an object is said to be uniform if it covers equal displacements in equal interval of time Non Uniform MotionThe motion of an object is said to be non uniform if it covers unequal displacements in equal intervals of time. Velocity. The rate of change in speed with respect to the time is called velocity of the object. It’s a vector quantity as we will as makes sense only when both its magnitude as we will as direction are defined Acceleration If the velocity changes from time to time, then the parameter which is responsible for change in velocity is called acceleration. In other words, it’s defined as the rate of change of velocity with respect to time. Like velocity, acceleration imparted on an object is also a vector quantity Uniform AccelerationIf the velocity of an object changes at a uniform rate, then the acceleration that causes the change in velocity is called uniform acceleration or constant acceleration. For example, the force of gravity imparts an acceleration uniformly which is called acceleration due to gravity.
