Physics and the Fair: Forces and Motion
... Physics and the Fair: Forces and Motion WHAT IS A FORCE? Forces change the way that objects move. A force can push or a pull an object, and is based on an interaction from another object. In his publication, “The Principia,” Sir Issac Newton defined three laws of motion, which describe much of what ...

Physics Review
... the motion of the object does not change. If an object is already at rest, it will remain at rest. If an object is moving, it will keep on moving. Balanced forces do not cause a change in an object’s motion. If all the forces acting on the object are not balanced, then the net force is greater than ...
