Multiple Choice

According to the article, what is one benefit of a seatbelt?

• It decreases the passenger’s inertia.

Multiple Choice

A car moves at a constant speed without changing direction. What HAS to be true about the forces on the car?

• A force is pushing the car in the direction it's moving.

• The forces on the car are balanced.

• The forces on the car are not balanced.

• Forces push on the car in all directions.

Multiple Choice

What is inertia?

• Objects changing their motion on their own.

• Objects moving in a straight line.

• Objects staying still when they are acted on by a force.

• Objects not changing motion unless acted on by an unbalanced force.

Multiple Choice

What is a force?

• a touch

• Gravity only

• a push or Pull

• power and energy

Multiple Choice

What is newton?

• The unit for force

• a push of pull

• force

• friction

Multiple Choice

A ball is sitting still on a plate. How could the ball start moving?

• The ball's inertia disppears.

• All the forces on the ball stop.

• A new, unbalanced force acts on the ball.

• A new, balanced force acts on the ball.

Multiple Choice

A driver stops suddenly at a red light. He is thrown forward against the seatbelt. Why?

• A force pushes him forward when he stops.

• A force pushes the whole car forward, including the driver.

• The force of the seatbelt pushes him backwards.

• The force of the brakes stops the car, but not the driver.

Multiple Choice

You are throwing a ball to your friend across the room. Which ball will take more force to throw?

• They are the same size, so they will take the same force.

• The bowling ball has a greater mass, so it will take more force.

• The basketball has a smaller mass, so it will take more force.
