What are Isaac Newton’s Laws of Motion?
Three core principles that provide an essential framework for understanding the mechanics of movement and force in sports.
These laws help in analysing the behavior of athletes and sports equipment under different conditions.
What does the First Law of Motion state?
Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless acted upon by an external force.
This property of resisting changes in motion is called inertia.
Provide an example of the First Law of Motion in sports.
A rugby ball will not move until kicked.
A diver maintains their motion when leaping off a diving board, only altering course due to external forces like gravity and water resistance.
What is the definition of the Second Law of Motion?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
What is the formula associated with the Second Law of Motion?
Force = Mass × Acceleration.
How does the Second Law of Motion apply to sports?
A heavier shot put requires more force to achieve the same acceleration as a lighter one.
The force a football player uses to kick a ball determines how far and fast the ball travels.
What does the Third Law of Motion state?
For every action, there is an equal and opposite reaction.
Provide a sporting implication of the Third Law of Motion.
A high jumper pushes down on the ground and the ground pushes back with an equal force, propelling them upward.
Rowers pull on the oars, and the reaction force of the water pushes the boat forward.
