Question

Which of the following statements applies to the motion of a ball rising and then falling in free fall?

I. The ball has constant acceleration as it moves upward.
II. The ball has constant acceleration at the top of its path.
III. The ball has constant acceleration as it moves downward.

Answer 1

Step-by-step explanation:

When a ball is rising or falling vertically upwards or downwards, the acceleration acting on the ball is always downwards and it is called acceleration due to gravity.

The acceleration due to gravity is the acceleration which is due to the earth's gravitational filed. On earth surface its value is 9.8 m/s^2 .

So, the acceleration acting on the ball is acceleration due to gravity which is acting vertically downwards.

Answer 2

the statements that apply to the motion of a ball rising and then falling in free fall is :
- The ball has constant acceleration as it moves upward
- The ball has constant acceleration at the top of its path
- The ball has constant acceleration as it moves downward
