FORCES

In science, force, usually means either a push or a pull.
Think of a game of ten pin bowling.
The moving object - the ball, exerts a pushing force against anything it hits - the ten pins.

Think of tugging on a rope.
The person in the picture is exerting  a  pulling force on his end of the rope.
