Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which statement best describes Newton's Third Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
For every action, there is an equal and opposite reaction.
Forces always occur in pairs, but they do not always act on different objects.
2. When a swimmer pushes water backward, the water pushes the swimmer forward. This is an example of:
Newton's First Law
Newton's Second Law
Newton's Third Law
Law of Conservation of Energy
3. Newton's Third Law states that for every action, there is an and reaction.
4. Action-reaction forces always act on objects.
5. The forces in an action-reaction pair are always in magnitude and in direction.
6. Identify the action-reaction pair when you kick a soccer ball. Clearly state which force is the action and which is the reaction.
7. Explain why a rocket is able to move in space, even though there is no air to push against.
8. If you push on a wall, the wall pushes back on you with a greater force.
True
False
9. Action and reaction forces cancel each other out because they are equal and opposite.
True
False
