Question

In our everyday life, we come across various types of motion give an example in which acceleration is against the direction of motion?

Answer 1

Acceleration:

1. Acceleration is the rate of change in velocity.
2. Unit of acceleration is $m/s^2$

Example in which acceleration is against the direction of motion:

1. When breaks are applied to a car in motion, its speed decreases. The acceleration produced in the car is against the direction of motion.
2. A ball is thrown vertically upward, in this case, acceleration is opposite to velocity.
