Question

The acceleration of a body depends on:

• A. The external force acting on the body only
• B. The mass of the body only
• C. Both the external force and the mass
• D. The displacement of the body only

Answer 1

Answer: (C)

Both the external force and the mass

$\text{Acceleration}=\frac{\text{External net force}}{\text{mass of the body}}$

So, the acceleration depends on both the external force and the mass.

Note: If the motion is uniform acceleration(general case) then the displacement depends on acceleration not vice-versa.

Option C is correct.
