Question

If mass of body and force acting on it both are doubled what happens to the acceleration?

Answer 1

Answer:

The acceleration remains unchanged.

Explanation:

Let the mass of the body, acceleration and force be m ,a and F.

Now as

F=ma

~> a=F/m. ........(I)

Now if m and F are doubled the mass becomes 2m and force become 2F.

Now

a=2F/2m

~> a =F/m

since it is same as in equation I

Hence acceleration remains unchanged.

Answer 2

Answer:

Let the mass of body be m and the force acted on it be f. Hence, when the mass and force on the body is doubled then, acceleration remains same.
