Question

The acceleration of a body may be doubled by doubling its:

• A. mass
• B. momentum
• C. velocity
• D. force acting on it

Answer 1

Answer: (D)

force acting on it

Acceleration $a=\frac{Force}{mass}$

Also $a=\frac{\Delta P}{\Delta t\times m}$, Where, $\Delta P$ is the change in momentum.

So to double the acceleration we need to $double$ the $force$ acting on it.
