Read each question carefully and answer to the best of your ability. Show all your work for calculations.

1. Newton's Third Law of Motion states that for every action, there is an equal and opposite  .

a

force

b

velocity

c

acceleration

d

momentum

2. When you push against a wall, the wall pushes back on you with a force that is:

a

Greater than your push

b

Less than your push

c

Equal to your push

d

Zero

3. When a rocket takes off, the action force is the expulsion of hot gases downward, and the reaction force is the rocket moving  .

4. The forces described in Newton's Third Law always act on   objects.

5. According to Newton's Third Law, action and reaction forces cancel each other out because they are equal and opposite.

T

True

F

False

6. If a bird flies, it pushes air downwards, and the air pushes the bird upwards. This is an example of Newton's Third Law.

T

True

F

False
