• push

A push or a pull is a...

• force
• position
• non-contact
• speed

An object's location, or where something is

• friction
• motion
• position
• magnetism

Two football players are pushing against each other, but neither of the players move.  Why?

• They are applying no force.
• One player is applying more force.
• They are applying the same amount of force.
