What is 5 W of Power?
400
is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
What is the definition of force?

Three children push against a large rock, but it does not move.
What is zero work?
400
The less time work is done.
What is greater Power?

A truck hits a car and moves it in the opposite direction.
What is momentum?
500
a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.
What is a screw?
500
Energy cannot be created nor destroyed.
What is the Law of Conservation of Energy?
