To investigate the effects of balanced and unbalanced forces, Jose and Gina test various objects and record the results. For this investigation, they stand on opposite sides of a large 10-pound wooden box and push against it toward one another.

The box will not move.
The box will move toward Gina.
The box will move toward Jose.
The box will lift off the ground.
For science class, your teacher gives you and your partner a ball. She asks you to figure out a way to balance forces that you apply to the ball. How do you and your partner show this?
Both of you pull with equal force on the same side of the ball.
Both of you push with equal force on the same side of the ball.
Both of you pull with equal force on opposite sides of the ball.
One person pulls and one person pushes with equal force on opposite sides of the ball.
Patrick was riding his new skateboard in the skate park. All of a sudden, he hit a small rock and his skateboard stopped. Patrick ended up falling off his skateboard and broke his arm. The small rock created an opposing force and made the skateboard stop because:
