Question

Take a ping-pong ball. Release it from a height on
a hard, smooth floor. You will observe that the ball
after striking the floor bounces several times. Try to
answer the following questions :
(a) What is the potential energy and kinetic energy
when you release the ball ? PE-ESK.EO
(b) Why does the ball bounce back after striking
the floor ?
(c) From where does the ball get the kinetic energy
for motion after striking the floor?
(d) What happens to the energy of the ball when
the ball stops bouncing ?​

Answer 1

Explanation:

Given Take a ping-pong ball. Release it from a height on a hard, smooth floor. You will observe that the ball  after striking the floor bounces several times. Try to  answer the following questions :

(a) What is the potential energy and kinetic energy

when you release the ball ?

(b) Why does the ball bounce back after striking

the floor ?

(c) From where does the ball get the kinetic energy

for motion after striking the floor?

(d) What happens to the energy of the ball when

the ball stops bouncing ?

• Now the ball is released from a height, so the ball has potential energy and the kinetic energy is zero since the ball is at rest.
• Now when the ball is released, potential energy is zero and kinetic energy is maximum.
• After striking the floor the ball bounces back since for every action there is an equal opposite reaction according to Newton’s third law of motion.
• Now from the ground which has potential energy.
• As the ball stops bouncing, the kinetic energy is being converted into potential energy and hence the speed decreases.
