Question

If a force is applied on an object in the direction of its motion, speed of the object ___.

• A. decreases
• B. increases
• C. doesn't change
• D. first decreases, then increases

Answer 1

The correct option is B increases

If a force is applied on an object in the direction of its motion, the speed of the object increases. Here the direction of the motion of the object and the direction of the force applied on the object is the same. Both will get added and results in increase in the speed of the object.
