Force Unit Review - 5th grade Science

(2) Mrs. Giet’s class is playing tug of war at recess. They decide to play boys against girls. There are 11 girls and 6 boys. As soon as the game began, the girls were able to move the rope to their side. Why?

• There was an equal amount of force pulling on each side making it unbalanced.

• There was an equal amount of force pushing on each side making it unbalanced.

• There was more force on the girls side making it unbalanced.

• There was less force on the girls side making it unbalanced.

What would most likely happen to the motion of the box if you poured oil on the ramp?

• It will slow the box because the force of friction will be increased.

• It will speed up the box because the force of friction will be increased.

• It will slow the box because the force of friction will be reduced.

• It will speed up the box because the force of friction will be reduced.

A car was traveling on a dirt road and on a concrete road. The car was able to travel on the concrete road without using as much force. Which description explains this scientific fact?

• The dirt road has more friction because the surface is not smooth.

• The concrete road has more friction because the surface is smoother.

• The concrete road has more gravity because the surface is not smooth.

• The concrete road has less gravity because the surface is not smooth.

What is the best description of what happened between A and B?

• The runner sat down.

• The runner slowed down.

• The runner sped up.

• The runner crossed the finish line.
