Newton's Laws of Motion Quiz

1. A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force. 2) When a body is acted upon by a net force, the body's acceleration multiplied by its mass is equal to the net force. 3) If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.

Isaac Newton first stated the three laws of motion in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), originally published in 1687.

Newton used his laws of motion to investigate and explain the motion of many physical objects and systems, which laid the foundation for classical mechanics.
