Newton's Law of Inertia describes the motion of-

• Objects at rest only
• Objects in motion only
• Objects at rest and objects that are in motion
• Objects without a mass and resist being set into motion

Which is the best example of Newton's First Law of Motion?

• a basketball thrown in the air falls to the ground
• a soccer ball remains motionless until it is kicked by a player
• a baseball player swings at an approaching ball
• an ice skater pushes back from a wall and moves backwards

What law of motion does this picture represent?

• Newtons 1st law
• Newtons 4th law 
• Newtons 3rd law 
• Newtons 2nd law

Which example best explains Newton's Third Law of Motion?

• When a glass slid across a table, it spilled water when it stopped suddenly.
• An engine used less work to move a lighter car than when it moved a heavier car.
• When you sit on a chair, your body exerts a downward force on the surface of the chair, while the chair exerts an equal and upward force on your body.
