Question

How does the K.E.of a moving body depends on its speed and mass

Answer 1

because the formula of K.E is 1/2mv^2 where m =mass
and v =speed
so if speed will change K.E will change.

Answer 2

Hi friend, here is the required answer:-
As we know that the formula of K.E. is
K.E.=1/2mv²
In the formula you can see that m, I.e. mass and v I.e. velocity is included. So, K.E. depends on mass and speed.
Hope this helps you...
