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

If you double the mass of an object with the same force apply on it, the acceleration will

• double
• cut in half
• the same
• zero
