Newton's Laws of Motion (Challenge Warm-Up)

What is Newton’s First Law of Motion also known as?

• The Law of Acceleration

• The Law of Gravity

• The Law of Inertia

• The Law of Force

Which of the following is an example of Newton’s First Law?

• A rocket launching

• A ball rolling and stopping due to friction

• A balloon popping

• A magnet pulling a nail

Which force keeps objects from sliding off a car seat when the car turns slowly?

• Gravity

• Friction

• Air resistance

• Inertia

Newton’s Second Law explains how:

• Forces cause motion

• Energy is created

• Objects always stay in motion

• Gravity disappears in space

Newton’s Third Law tells us that:

• A force is always needed to keep something moving

• Every action has an equal and opposite reaction

• Gravity always pulls downward

• Mass increases force
