According to Newton's first law, what will an object at rest do?

• Stay at rest unless acted upon

• Fall downward

• Move randomly

• Accelerate on its own

What happens to a dodgeball in motion if no external force is applied?

• It speeds up

• It stops immediately

• It changes direction

• It stays in motion

What does Newton's second law state about force?

• Force equals mass times acceleration

• Force equals acceleration minus mass

• Force equals mass plus acceleration

• Force equals mass divided by acceleration
