Which law of motion predicts that a moving hockey puck will continue to move in the same direction at the same speed unless acted upon by another force?

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Law of Universal Gravitation

Answer explanation

Newton's First Law of Motion states that an object in motion will stay in motion unless acted upon by an external force, explaining why a moving hockey puck will continue in the same direction at the same speed.

According to Newton's Third Law of Motion, if Mike pushes down on the springboard to being his dive, what is the reaction force?

• Mike splashing into the water

• The springboard pushing Mike into the air

• The height of the water when Mike enters the water

• The sound the board makes as he pushes into the air

Answer explanation

According to Newton's Third Law of Motion, the reaction force when Mike pushes down on the springboard is the springboard pushing Mike into the air.
