Newton's First Law of Motion

1. A force that opposes, or pushes back against, an object moving past another object

• gravity
• friction
• inertia
• mass

2. An object at rest will stay at rest unless an unbalanced force acts on it.

• True
• False

3. An object that is changing position (location) is

• at rest
• in motion

4. What is Newton's First Law of Motion?

• F=m x a
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force.
• Friction

5. What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

6. Calculate the net force shown in the diagram?

• 6 N, moving to the Right
• 6 N, moving to the Left
• 9 N, moving to the Right
• 9N, moving to the Left

8. Jose and Gina test what they have learned on balanced and unbalanced forces. Jose applies 10 Newtons of forces to one side of a box and Gina applying 12 Newtons of force to the other side of the box. What will happen to the box?

• A. The box does not moves.
• B. The box moves toward Gina.
• C. The box moves toward Jose.
• D. The force crumples the box.

10. Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
