Force is a push or pull that affects the motion of an object. Motion is the way an object changes its position over time. Forces can be balanced or unbalanced, resulting in either no motion or accelerated motion.
Force and Motion
Force: A push or pull on an object that causes it to move, stop, or change direction. Motion: The act or process of changing place or position. Acceleration: The rate of change in an object's velocity over a period of time.
When you push on an object, the object pushes back with the same amount of force. This is known as Newton's third law of motion. The force of gravity is the same for all objects regardless of size or mass. The force of friction between two objects depends on the surface area in contact and the nature of the surface.
