NEETPhysicsWork, Power and Energy
Assertion (A): When we bounce a ball on the ground, it comes to rest after a few bounces, losing all its energy. This is an example of violation of conservation of energy. Reason (R): Energy can change from one form to another but the total energy is always conserved. Which of the following is true?
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true, but (R) is not the correct explanation of (A)
- C(A) is true, but (R) is false
- D(A) is false, but (R) is true
Correct answer
D. (A) is false, but (R) is true
Step-by-step solution
The moment ball coming to rest mean that the initial potential energy of the ball gets converted to kinetic energy and when this energy is being used to counteract the energy loss during its motion.
