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. You and your partner do this by:
A. Both of you pull with equal force on opposite sides of the ball.
B. Both of you pull with equal force on the same side of the ball.
C. One person pulls and one person pushes with equal force on opposite sides of the ball.
D. Both of you push with equal force on the same side of the ball.

A.Both of you pull with equal force on opposite sides of the ball.

Explanation:

Balanced forces means that the total force or the sum of the force done on the object should be equal to 0 newtons or in other words, it should not be moving.

Force is defined as the push or pull on an object. For both people to balance out the forces on the ball while both applying a force, you need to do this from opposite sides.

You could either pull with equal forces on opposite sides of the ball or you can push with equal forces on opposite sides of the ball.

→ ball ←

← ball →

For the other choices, if you both push or pull on the same side, the ball would move that direction because there is no opposing force.

ball → →

If one pushes while the other pulls on opposite sides, it will move the direction you are pulling and pushing.

→ ball →
