Newton's Laws of Motion

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

• An object at rest tends to stay at rest.
• For every action there is an equal and opposite reaction.
• The acceleration of an object is based on the force applied.
• An object continues its motion until an unbalanced force is applied.

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

As the wheels of a train push down on the track, the track pushes back against the wheels. Which of Newton's laws is used to explain these forces.

• An object at rest tends to stay at rest unless acted upon by an unbalanced force.
• The net force of an object is its mass times its acceleration.
• For every action, there is an equal and opposite reaction.
• Any 2 objects exert a gravitational force of attraction on each other.
