SC.6.P.13.3 Force & Motion

Which of the following statements best explains why only the student who throws the bowling ball feels a noticeable push backward?

• The bowling ball exerts a much larger reaction force due to its larger mass.

• The bowling ball undergoes a much larger acceleration due to its larger mass.

• The bowling ball converts more inertia into kinetic energy due to its larger mass.

• The bowling ball requires more force to overcome gravity due to its larger mass.

A space probe is launched from the surface of Earth into space. After 30 minutes, the space probe runs out of fuel and the rocket engine stops, but the space probe continues moving at a constant speed. What concept explains this phenomenon?

• friction

• gravity

• inertia

• mass

A swimmer pushes off of a raft floating next to her in order to swim to the other side of the pool. According to Newton’s Third Law of Motion, what will happen to the floating raft?

• The raft will remain stationary in the water.

• The raft will move in the same direction as the swimmer.

• The raft will move in the opposite direction of the swimmer.

• The raft will slowly move to the right or left of the swimmer depending on which foot was used.

A person sitting in a rolling chair at rest throws a basketball forward. Since the person and the rolling chair have a greater mass than the basketball, how will the person and the rolling chair respond?

• They will have the same forward momentum as the basketball.

• They will move backward at a lower speed than the basketball moves forward.

• They will move backward at a higher speed than the basketball moves forward.

• They will travel the same distance as the basketball travels but in the opposite direction.
