Question

If a ball is thrown up, which of the

following does not change?

A. Acceleration

B. Speed

C. Potential energy

D. Distance​

Answer 1

Ans. A

Sol. • When a ball is thrown up,

acceleration does not change.

Acceleration is the rate of change of

velocity.

• The acceleration does not change due to

the presence of air resistance and

gravitational force which pulls the ball

downwards with the same acceleration in

which the ball goes up.

• So, the acceleration remains g towards

earth.
