Back

Law of Conservation of Energy

Front

Energy can not just appear out of nowhere nor can it disappear in a closed system; it must always take on another form.

Friction Force

Front

The component of the contact force that is parallel to the surface. (When an object is in contact with a surface, the surface exerts a contact force on the object).
