Newton's Third Law of Motion

An astronaut is floating freely in space and wants to release a spent fuel container that has the same mass as he does. Which statement best describes what will happen to the astronaut and the container?

• The astronaut will remain still, and the container will fly away at the speed given to it by the astronaut.

• The astronaut will recoil slightly but quickly stop, and the container will move away at a constant speed.

• The astronaut will move in a direction opposite to that of a container and move just as fast as the container

• The astronaut and the container will remain still since a surface is required to push off in order to throw an object.

A student releases the air from the inflated balloon, as the air released, the balloon moves forward, as shown. How can the student best classify the action and reaction forces of the balloon according to Newton's 3rd law of motion?

• Action: balloon contracts, forcing air outward through the opening; Reaction: movement of balloon in the direction opposite of the escaping air

• Action: balloon contracts, pulling air inward through opening; Reaction: movement of balloon in the direction of the escaping air

• Action: balloon expands, pulling air inward through the opening; Reaction: movement of balloon in the direction opposite of the escaping air

• Action: balloon expands, forcing air outward through the opening; Reaction: movement of balloon in the direction of the escaping air

A person is paddling a canoe with an oar across a calm lake on a summer afternoon. The oar exerts an action force on the water. What can be inferred from this scenario?

• The water exerts no reaction force on the oar because the water simply slides around the oar.

• The water exerts a greater reaction force on the oar because it provides resistance for the oar and creates drag as the canoe moves.

• The water exerts a lesser reaction force on the oar since water is a fluid and does not retain a definite shape when force is applied.

• The water exerts an equal reaction force on the oar regardless of the velocity of the canoe.

A student reads two examples regarding action and reaction and lists several patterns about the forces. Which pattern(s) listed by the student is(are) correct?

• 1 only

• 3 only

• 1 and 2

• 1 and 3
