ewton’s Laws Newton s Laws 1 st Law – If an object is in motion, it will remain in motion. If an object is at rest, it will remain at rest, unless a force acts upon it. – When the sum of forces acting on an object is zero, the object will remain at rest if initially at rest. 2 nd Law – When the sum of forces acting on an object is not zero, the sum of the forces is equal to the product of ,q p the mass and its acceleration. –F =
