What does Newton's First Law of Motion state about an object at rest?

• It will change its position without any force applied
• It will eventually move on its own over time
• It will oscillate indefinitely in place
• It will remain at rest unless acted on by an external force

Which of the following best describes Newton's Second Law of Motion?

• Energy cannot be created or destroyed in an isolated system
• For every action, there is an equal and opposite reaction
• An object in motion tends to stay in motion unless acted on
• Force equals mass times acceleration
