Question
Explain the following concept in your own words with everyday examples:
Acceleration
Advertisements
Solution
The rate of change of velocity is known as acceleration. It is a vector quantity.
For example, if a car is moving on a straight with variable speed, it will possess some acceleration. In case the speed of the car remains the same but the direction of the car changes, then also the car would be accelerating.
