Connecting Motion with Force
... Force- a push or pull one body exerts on another. -Force does not always change velocity. Balanced forces- forces on an object that are equal in size and opposite in direction. Ex: Tug of War. ...

Circular Motion
... circular motion is continually accelerating. The direction and velocity of a particle moving in a circular path of radius r are shown at two instants in the figure. The vectors are the same size because the velocity is constant but the changing direction means acceleration is occurring. ...

Newton`s Second Law
... Newton’s First Law: An object at rest remains at rest, and an object in motion remains in motion with the same speed and direction (maintains its velocity) unless it experiences an unbalanced force. Example: A soccer ball resting on the grass remains motionless until a force is applied (a kick). Th ...
