Explain Newtons 3 laws
First Law (Law of Inertia):
An object will stay still or keep moving in a straight line unless something makes it change.
Sporting Example: A soccer ball will stay at rest on the field until a player kicks it.
Second Law (Law of Acceleration):
The acceleration of an object depends on the force applied and its mass.
Sporting Example: The harder a tennis player hits the ball, the faster it travels across the court
Third Law (Action and Reaction):
For every action, there's an equal and opposite reaction.
Sporting Example: When a swimmer pushes against the water, the water pushes them forward.
