Question

Which of the following effects is NOT seen when a player kicks a moving football?

• A. Change in direction of the football
• B. Change in mass of the football
• C. Change in shape of the football
• D. Change in speed of the football

Answer 1

The correct option is B Change in mass of the football

When a football is kicked, a force is applied on it. The shape of the football can change a little bit or we can say it can get deformed a bit. Hence option A, change in shape of the football​, is not the correct option.
When a football is kicked, its direction can be changed. Hence option B, change in direction of the football​, is not the correct option.
The football’s mass remains constant and it is not changed by kicking it. Hence option C, change in mass of the football​, is the correct option.
Earlier the football was moving with a certain speed. When it was kicked, its speed was changed. Hence option D, change in speed of the football​, is not the correct option.
