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 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.
- Non-uniform acceleration: When an object is travelling 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.
