Newton's 3 Laws

What does Newton's First Law, also known as the Law of Inertia, state about objects at rest?

• They will eventually move on their own

• They change direction spontaneously

• They will remain at rest unless acted upon by an external force

• They will move unless stopped

According to Newton's Second Law, what must be applied to a bicycle to make it accelerate?

• A reduction in speed

• A force

• A decrease in mass

• Less effort on the pedals

Why is it harder to pedal a heavier bicycle at the same rate as a lighter one?

• Bicycle color affects speed

• Less gravitational pull

• More force is required

• Wheels are larger

What happens when the bicycle tires push backwards against the ground?

• The tires wear out faster

• The bicycle moves sideways

• The ground moves significantly

• The bicycle is propelled forward

What illustrates Newton's Third Law when you pedal a bicycle?

• The bicycle slowing down

• The equal and opposite reaction of the ground

• The bicycle moving in reverse

• Increased pedal resistance
