If you increase the force on an object what happens to acceleration?

• increases

• decreases

• remains the same

• the mass doubles

• 1kg box

• 100 kg box

• they will accelerate at the same rate

A stationary bumper car is set in motion by the outside force of another bumper car colliding with it.

• Law of Inertia

• Law of Mass and Acceleration

• Law of action and reaction

The harder you hit a baseball, the faster it accelerates.

• Law of Inertia

• Law of Mass and Acceleration

• Law of action and reaction

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.
