Answer: Acceleration is basically the rate at which the velocity changes in relation with time. Acceleration is a vector quantity due to the facts that it has magnitude and direction, both.
Uniform Acceleration
The term “uniform acceleration” refers to an item travelling in a straight path with an increase in velocity at equal intervals of time.
Uniform acceleration may be seen in the free-falling of an item.
Non- Uniform Acceleration
Non-uniform acceleration occurs when an item accelerates at a constant rate but not at equal intervals of time.
Non-uniform acceleration is demonstrated by a bus moving or departing from a bus stop.
