Question

what happens to the motion of an object when unbalanced forces act on it? a. the object does not move b. only objects speed changes c. only the objects direction of motion changes d. the objects speed and/or direction of motion may change

Explanation:

According to Newton's first - law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When unbalanced forces act on an object, its speed and/or direction of motion changes.

Answer:

D. The object's speed and/or direction of motion may change
