Which statement is true about unbalanced forces?

Question

A. They have no impact on an object in motion.
B. They only change an object's direction.
C. They only change an object's speed
D. They can change both an object's speed and direction.

Answer 1

The correct statement is:

D. They can change both an object's speed and direction.

Unbalanced forces result in a net force acting on an object, which can cause changes in both the object's speed (acceleration or deceleration) and its direction of motion.
