A person steps out of the boat and onto the dock.  As the person moves forward onto the dock, the boat moves backward.  Which statement best describes the backward motion of the boat as the person steps forward?

• For every action there is an equal and opposite reaction.

• Every mass exerts a force on every other mass.

• An object at rest tends to stay at rest.

• Friction opposes the motion of an object.

When you jump off a small boat into the water, why does the boat move backwards?

• Because of the water's resistance.

• Because of your weight.

• Because of the reaction force from your jump.

A student throws a ball against a wall.  Which statement best explains what is happening in the picture.

• The energy of the ball is destroyed as it strikes the wall.

• The energy of the ball becomes negative as it hits the wall.

• The force from the wall on the ball is equal and opposite to the force from the ball on the wall.

• The force exerted by the ball on the wall is greater than the force exerted by the wall on the ball.

A bowling ball is rolled with a certain speed and strikes a bowling pin with a force indicated by the arrow in this illustration. When the bowling ball strikes the bowling pin, the force applied by the pin to the ball -

• depends on the mass of the bowling pin.

• is equal to the force applied by the ball.

• must be zero, since the pin is not moving.

• is equal to the force of gravity on both.
