A tennis ball changes direction after a player hits the ball with a tennis racket. This change in direction is a result of ______________

• noncontact force

• gravity

• balanced forces

• contact force

EQUAL forces acting on an object in opposite directions.

NGSS.3-PS2-1

A force between two surfaces that are sliding, or trying to slide, across each other. This force causes motion to slow down and (eventually) come to a stop.

• energy

• friction

• work

A force that pulls objects toward each other. The reason why "What goes up, must come down." Without this force we would all be floating around...
