Question

When a body is acted by a constant force, then which of the following quantities remain constant

• A. Velocity
• B. Acceleration
• C. Momentum
• D. None of these

Answer 1

Answer: (B)

Acceleration

$F=ma$

For a given body if $F=$ constant then $a=$ constant.

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force
