A person is pushed forward into their seatbelt when a car stops. This is an example of --

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?

• The car with the smaller mass will require less force to stop than the car with the larger mass

• The car with the larger mass will maintain its velocity while traveling down the hill

• The car with the smaller mass will take longer to stop than the car with the larger mass

• The car with the larger mass will have less inertia than the car with the smaller mass
