Newton's 1st Laws of Motion Quiz

What does Newton's first law of motion state?

• An object at rest stays at rest and an object in motion stays in motion at a constant velocity

• An object at rest stays at rest and an object in motion accelerates

• An object at rest accelerates and an object in motion stays in motion at a constant velocity

• An object at rest accelerates and an object in motion decelerates

How does the airbag in the photo affect the motion of the driver in the car?

• It increases the inertia of the driver

• It decreases the inertia of the driver

• It provides a force to stop the driver

• It provides a force to accelerate the driver

What do you expect to happen to the phone when the car turns?

• The phone will stay in the same position relative to the dashboard and turn with the car because of inertia

• The phone will move in a straight line because a force is pushing the phone in a straight line

• The phone will continue to move in a straight line because of inertia. The force of friction is not enough to change the motion of the phone

• The phone will stay in the same position relative to the dashboard and turn with the car because of friction

How does Newton’s first law apply to the motion of the penguins sliding on the frozen ground?

• The penguins will continue to slide in a straight line because of inertia

• The penguins will move in a circular path due to the force of friction

• The penguins will stop sliding due to the force of friction

• The penguins will accelerate due to the force of friction

Consider a small tennis ball and a large bowling ball. Which one will require more effort to push, assuming they are made of the same material?

• The tennis ball requires more effort because it has less mass

• The tennis ball requires less effort because it has less mass

• The bowling ball requires more effort because it has more mass

• The bowling ball requires less effort because it has more mass
