Isaac Newton

Sir Isaac Newton was an English physicist and mathematician who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution.

Newton's 1st Law

An object in motion will stay in motion will stay in motion will stay in motion unless acted upon by an outside force.

An object at rest will stay at rest unless acted upon by an outside force.

Example of Newton's 1st Law

When a soccer player gets a free penalty kick the soccer ball will stay on the line on the ground until the soccer player kicks the ball into the goal.

Newton's 2nd Law

Force = Mass x Acceleration

Example of Newton's 2nd law

When you kick a soccer ball the acceleration of the ball during the time your foot is contacting it will be proportional to how hard you kick it.

Newton's 3rd Law

Action = Reaction

For every action there is an equal or opposite reaction.

Example of Newton's 3rd law

When a soccer player heads the ball, the ball is exerting the same force on your head as your head exerts on the ball.
