Q: What is Newton’s First Law of Motion?
A: Newton’s First Law states that an object will remain at rest, or continue to move in a straight line at constant speed, unless acted upon by an external force.
Did you know?
It is Newton’s First Law that explains why passengers lurch forward in a car when it suddenly stops—their bodies tend to keep moving at the same speed until the seatbelt (an external force) stops them. Similarly, in space, a spaceship can keep moving forever in a straight line without fuel because there’s almost no friction or air resistance to slow it down.
