Which of the following best explains the motion of the car represented in section “D” of the graph?
The car is stopped in section “D”.
The car is going faster than it was in section “B”.
The car is moving on level ground in section “D”.
The car is higher than it was in section “B”.
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 student wishes to design an investigation to determine the effect of changing the mass of an object when an unbalanced force is applied to the object. What should she use as the independent variable in her investigation?
time
force
mass
speed
Which of the following best explains which material would work best for the warehouse floor?
The tile because it had the least friction.
The wood because it would be easiest to push the boxes on.
The dirt because it has the least friction.
The asphalt because it has the most friction.
(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.
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.

The diagram above shows four identical boxes filled with different materials that need to be pushed across the room. Equal force is applied to each box for 15 seconds. Which box will move the farthest after 15 seconds?
A. Box 1
B. Box 2
C. Box 3
D. Box 4
Why do the boxes move different distances when pushed with the same amount of force?
A. Lighter objects have increased friction with the floor.
B. Heavier objects have increased friction with the floor.
C. Smooth objects have more friction with the floor.
D. Rough objects have more friction with the floor.
