Which statement best explains Newton's Third Law of 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

An object is resting motionless on a surface. According to Newton's 1st Law, the object will only start to move if

• the net forces on the object equal zero
• an unbalanced force is applied to the object
• the upward force of the object is equal to its acceleration
• two forces that are equal and opposite are applied to the object
