1) Mutt and Jeff are running along a path each pushing a cart loaded with rocks. If Mutt's
wagon has a mass two times greater than Jeff's and they want to stay together, arriving at their
destination at the same time, what must happen?
A)
B)
C)
D)
Jeff should slow down so Mutt can catch up.
Mutt must use half as much force to push his cart.
Mutt must use twice as much force to push his cart.
Mutt and Jeff will use the same force, but Mutt will take bigger steps.
2) In baseball, a home run means the batter has hit the baseball into the stands, beyond the
baseball field. Compare the force of the batter when bunting the ball into the in-field versus
hitting a grand slam.
A)
B)
C)
D)
There is no way to estimate the batter's force.
The force is much less when bunting into the in-field.
The force of the batters in each case is about the same.
The force of the batter is much less when hitting the ball out of the park.
3) Four boxes of increasing size and weight must be pushed up a ramp. To push the boxes at the
same speed, what must you do?
A) Push the boxes with the same force, smoothly up the ramp.
The larger and heavier the box, the more force you must use
B)
when pushing.
Push the boxes with the same force, at exactly the same speed,
C)
up the ramp.
Push the largest box with the most force; push the others with
D)
about the same force.

Which baseball bat will hit the ball the longest distance? Students in Mr. Brant's class designed
an experiment to test this research question. The table shows the trial data they collected for the
different bats. Which bat, based on this data, would be the best choice if you were interested in
using low force to move the ball?
A) wood
B) alloy
C) aluminum
D) alloy or aluminum

seems to be pushed back against the seat. Which word best explains why your body seemed to
be pushed backward against the seat?

B) vector
D) gravity
7) This graph shows that as an object’s mass increases its
A) inertia increases.
C) acceleration increases.
B) inertia decreases.
D) acceleration decreases.
8) A cup of coffee sits on the dashboard of an
automobile. The car goes around a sharp curve. Even
though you hold the cup still, coffee still splashes out.
This can best be explained due to
A) density. B) friction. C) gravity.
D) inertia.
9) Two classes of students line up for a tug of war. If both classes have the same number of
students on a team, what other factor is very important so one team can win?
A) total mass of each team
C) age of students on each team
B) condition of the ground
D) height of students of each team

What answer choice BEST explains why this occurred?
A) The train ran out of momentum.
B) The opposing force of friction stopped the train.
C) The natural state of the train is not to be in motion.
D) The force of gravity slowed the train until it stopped.
11) A basketball rolls to a stop along a gym floor without anyone touching it. What answer
choice BEST explains why this occurred?
A) The initial force that started the ball ran out.
B) The opposing force of friction stopped the ball.
C) The natural state of the ball is not to be in motion.

13) You are holding a full bowl of hot soup while standing in the kitchen. As you begin
moving, some of the soup spills out of the bowl onto the floor. Upon reflection, you realize that
A) the soup spilled because of air resistance.
B) if you had traveled faster this wouldn't have happened.
C) the soup wanted to stay where it was, but you moved the bowl.
