According to Newton’s First Law of Motion, an object at rest stays at rest unless acted upon by what?
AGravity only
BIts own mass
CFriction alone
DAn unbalanced external force
Explanation
Newton’s First Law, also called the law of inertia, states that an object stays at rest or continues moving at constant velocity unless an unbalanced external force acts on it. This is why passengers lurch forward when a car suddenly brakes, since their bodies continue moving due to inertia. A ball rolling to a stop is also explained by an external force, namely friction.
