Example When you are riding a bicycle on a level path and start to free-wheel, you can keep up an almost constant velocity force some time. But eventually you will slow down, partly because of air resistance. dire ...

Motion
... a book is being slid across the table there are 4 forces acting upon the book. The table and gravity are equal so the book does not move up or down. The push of the book acts in one direction and friction acts in the opposite direction The push is a bigger force, so it causes the book to move ...

Motion, Forces, and Simple Machines
... States: An object at rest stays at rest unless an unbalanced force acts on it. *An object moving in a straight line at constant speed will continue doing that unless acted on by a force. This force is called friction. It is a force that resists motion between 2 surfaces that are in contact. It alway ...

Objective:
... A toy car which is moving at a constant velocity accelerates when it is pulled using an elastic string. c) Slows down a moving object. When a vehicle moves from a smooth surface to a rough surface, the force of friction retards the motion of the vehicle. d) Stops the motion of an object. When a car ...
