Newton's First Law of Motion is known as the Law of _____

• Friction

• Mass

• Inertia

• Gravity

Which type of force(s) will cause a change an object's motion?

• equal forces

• zero net force

• balanced forces

• unbalanced forces

What is Newton's First Law of Motion?

• F=ma

• Every action has an equal and opposite reaction

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

• Energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.

This equation goes with which law?

• Newton's first law of motion
• Newton's second law of motion
• Newton's third law of motion
• None of these
