Question

A player throws a ball in vertical upwards direction. The direction of acceleration during upwards motion of the ball is ___________.

Answer 1

Explanation:

1. Acceleration:

• It can be defined as the rate of change of velocity with respect to time.
• It is a vector quantity.
• SI unit of acceleration is $\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s^2$}\right.$.

2. Direction of acceleration during upwards motion of ball:

• If an object is speeding up, then the direction of acceleration is in the same direction as the velocity.
• If an object is slowing down, then the direction of acceleration is in the opposite direction of the velocity, i.e., the body is in deceleration.
• So, when we throw the ball upwards, its speed retards gradually by the acceleration due to gravity which acts in the downward direction.

Final Answer:

Thus, when a player throws a ball in a vertical upwards direction, the direction of acceleration during the upwards motion of the ball is vertically downwards.
