Acceleration is defined as the rate of change of velocity and is an example of a vector quantity. Following are the types of acceleration:
Uniform acceleration: When an object is traveling 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.
Non-uniform acceleration: When an object is traveling with an increase in velocity but not at the equal intervals of time is known as non-uniform acceleration. Bus moving or leaving from the bus stop is an example of non-uniform acceleration.
Instantaneous acceleration: Acceleration of an object at any instant of time is known as instantaneous acceleration.
Average acceleration : The average acceleration over a period of time is defined as the total change in velocity in the given interval divided by the total time taken for the change. For a given interval of time, it is denoted as ā.
Difference Between Uniform and Non-uniform Motion
The basic difference between uniform and non-uniform motion is that the former represents the motion in which the moving body covers the same distance in the same time, but in the case of latter, the body travels unequal distances at the same time.
Difference Between Instantaneous acceleration and Average acceleration
Average acceleration is the notified change in velocity for the whole journey. Whereas the instantaneous acceleration is the acceleration due motion of the moving body at every instant. If the body is moving along a variable force field would feel different instantaneous acceleration with a different average one. For, a body moving under a constant force field would feel both of them to be the same eg. acceleration under gravity for some km above earth.
