Question
Physics Question on Kinetic Energy
The change in kinetic energy of a particle is equal to the work done on it by the net force. Change in kinetic energy of particle is equal to the work done only in case of a system of one particle.
A
if both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
B
if both Assertion and Reason are true but the Reason is nor the correct explanation of the Assertion
C
if Assertion is true but Reason is false
D
if Assertion and Reason are false
Answer
if Assertion is true but Reason is false
Explanation
Solution
Change in kinetic energy = work done by net force The relationship is valid for particle as well as system of particles.
