Four different students take turns pushing a large, heavy ball on the school parking lot. What is the best way to determine which student used the most force to push the ball?

• compare the sizes of the students

• compare the ages of the students

• compare the distances that the ball rolled

• compare the number of times the ball was rolled

Carey left a bowling ball and kickball outside on a windy day. Which best explains why the kickball moved but the bowling ball did not?

• The kickball has less mass so it was easier to move.

• The force of gravity acting on the bowling ball is greater.

• The mass of the kickball is greater so it is easier to move.

• The force of gravity acting on the kickball is greater.

Katie sits on the ground and rests her hands on a bowling ball in front of her. She uses all her force to push the bowling ball away from her body. Next, Katie rests her hands on a soccer ball situated in front of her at the same location. She uses all her force to push the soccer away from her body. How does the movement of the two balls contrast?

• The soccer ball accelerates faster and moves a greater distance because more force is acting on it.

• The soccer ball accelerates faster and moves a greater distance because it has less mass.

• The bowling ball accelerates faster and moves a greater distance because it has more mass.

• The bowling ball accelerates slower and moves a shorter distance because less force is acting on it.

Kaneesha pushes a toy truck and lets it roll across a flat surface. She measures the distance it travels. Kaneesha repeats this for several trials, using the same amount of force each time, but she adds different numbers of wood blocks of identical mass to her truck. Kaneesha’s results are shown in the following table. Which measurement is likely to be closest to the result for Kaneesha’s trial with 2 wood blocks?

• 12 cm

• 30 cm

• 57 cm

• 98 cm

Bianca pushes an empty box across a flat surface with little effort. She then fills the box up with books and tries to push it. What will most likely happen?

• The box will be easier to move because Bianca’s push will have less effect on the heavier box.

• The box will be easier to move because Bianca’s push will have a greater effect on the heavier box.

• The box will be harder to move because Bianca’s push will have less effect on the heavier box.

• The box will be harder to move because Bianca’s push will have a greater effect on the heavier box.
