Question

How will the kinetic energy of a body change if it's velocity is increased by 4 times

I'm in class 7 so I want the explanation with my standard ​​

Answer 1

Answer:

P is proportional to the square root of kinetic energy. Since 2 and m are considered as constants. Therefore, we can say that kinetic energy increased by four times. Therefore, when the kinetic energy increases by four times, then the moment will increase by two times.

Answer 2

Answer:

Hiii

how are you

good morning
