Newton’s Law of Motion

First Law

Law of Inertia.

Newton's first law states that an object at rest will remain at rest, an object in  motion will continue in motion with a constant velocity in a straight line unless acted upon by an external force.

Second Law

Acceleration. 

Newton’s second law relates the force applied to an object, the mass of the object, and the resulting acceleration. It is often expressed a the formula F = ma

Action - Reaction

Newton’s third law states that for every action, there is an equal and opposite reaction.

First Law - What example is correct

When a player is running on the court, they will keep moving unless they are stopped by a defensive player or they apply a force to change their direction.

Second Law - What example is correct

To make the ball accelerate (eg, when dribbling or shooting), a player must apply force

Third Law - What example is correct

When a player passes the ball, the action of pushing the ball results in an equal and opposite reaction, which causes the player to move backward slightly.
