The 5th graders were playing a game of tug-of-war.  The class was divided equally with half the class on one side of the rope and the other half on the opposite side.  For 5 minutes the students pulled and pulled but neither side could pull the flag to one side or the other.  Choose the description of the forces during the 5th grade tug-of-war.

• The forces were unbalanced in the game.

• The forces were friction, gravity, and chemical energy.

• The students all had the same amount of strength.

• The forces were balanced in the game.

What is a contact force?

• A force that touches the object to make it move or change directions

• force that does not touch the object to make it move or change direction.

During a science experiment, a student dropped a metal ball from a height of 150 m. The graph shows the distance the metal ball traveled from its initial position to where it hit the ground.

What information does the graph give you about the speed of the metal ball over time?

• The ball travels at a constant speed.

• The speed of the ball increases over time.

• The speed of the ball decreases over time.

• e speed of the ball increases at first, and then decreases as time increases.
