Newton's Laws and Forces Quiz

Newton’s First Law is also called the law of…

• Acceleration

• Inertia

• Gravity

• Force

Which situation BEST shows Newton’s First Law?

• A ball rolling until friction slows it

• A ball changing shape when kicked

• A ball bouncing higher than it fell

• A ball getting heavier when it rolls

Newton’s Second Law can be summarized as:

• F = m + a

• F = m ÷ a

• F = m × a

• F = a ÷ m

A 0.5 kg object accelerates at 4 m/s². What is the net force?

• 0.5 N

• 2 N

• 8 N

• 12 N
