Question

If the mass of a moving body is doubled, how
many times will the kinetic energy increase?​

Answer 1

Answer:

Kinetic energy of a body of given mass, is directly proportiional to its square of its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units. and percentage increase in kinetic energy is 400−100=300%

Answer 2

Answer:

4 times

Explanation: HERE YOUR ANSWER

The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy becomes 4 times.
