Force & Motion (BI.13) Practice

Natalie dropped an object out of a window. What force caused it to fall toward the ground?

• The friction force of the air moved it downward.

• The force of Earth's gravity pulled it downward.

• Natalie must have pulled it down before she let go.

• Natalie must have pushed it down before she let go.

Jared pushed a box with 10 kilograms of parts across the floor with a certain force for 5 seconds. Then he took 5 kilograms of parts out of the box and pushed on it with the same force for 5 seconds. What was the result?

• The box moved the same distance both times.

• Both boxes moved. The 5-kg box moved farther than the 10-kg box.

• Both boxes moved. The 10-kg box moved farther than the 5-kg box.

• The 10-kg box moved to a different place, but the 5-kg box did not move at all.

Brianna tries to pick up a box, but the box does not move. Why not?

• Friction holds the box to the ground.

• The forces acting on the box are unbalanced.

• Brianna's mass is equal to the mass of the box.

• Brianna is not using enough force to overcome the force of gravity on the box.

Rick and Corey are racing side-by-side on identical one-speed bikes. Corey starts to apply more force to his pedals than Rick. What is most likely happening?

• Corey is getting tired.

• Corey is starting to go faster than Rick.

• Corey is allowing friction to slow him down.

• Corey is increasing the force of gravity against his bike.
