Question

Change in speed would continue as long as an unbalanced force is applied.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation:

When an unbalanced force is applied to an object, the acceleration of the body changes according to the equation $\mathrm{F}=\mathrm{ma}$, where,

m is the mass of the body on which the force is applied and

a is the acceleration of the body on which the force is applied because the mass of a body is constant and cannot change.

1. The body's velocity/speed changes as a result of the change in acceleration.
2. This velocity change is in the same direction as the applied force.

Therefore, if an unbalanced force is applied, the speed change will last as long as the force is there.
