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 can cause a moving object to increase its speed in a forward direction?

• a force pushing on the object from the opposite direction

• force that moves continuously in the same direction as object

• an increase in the mass of the object
