Isaac Newton
First, let’s start with some history on Isaac Newton himself. Newton was the physicist and mathematician who laid out the foundations for calculus, a form of math. Quite contrary to the public belief, Newton did not discover gravity when an apple fell on his head. That is just a fable. Rather it was a complicated math equation that led him to that discovery. He was knighted by the Queen in 1705. Newton’s discoveries led to rocket science, and why a ball will eventually stop rolling! He was brilliant. He was master of the mint, and at the age of 60, he was made leader of the Royal Society. He died March 31st, 1727 at the age of 84.

Isaac Newton’s First Law Of Motion
Now back to his first law of motion. Newton made three laws of motion in his life, but I’m talking just about the first one. The first law is centered mainly on inertia. Inertia is the fact that an object at rest remains at rest. An object in motion will remain in motion. It also states that to stop a moving object or to move a resting object a force is required. An example of this would be a rolling ball hitting the wall and stopping. This would be a force stopping a moving object. A rolling ball, if not faced with friction, air resistance or wind would roll on forever. Another example of this would be a hand pushing that ball away from the wall. This would be an example of a force moving a resting object from its original position.

Examples Of The First Law In The Real World
Say Cristiano Ronaldo shoots the soccer ball at a goal. This would be applying a force to a resting object. Then, Peter Cesh grabs the ball out of the air. This would be a force applied in an opposite direction to stop a ball. Rockets and space shuttles are designed using the principals of inertia. The rockets need a tremendous amount of power to escape earth’s pull of gravity. But once in space, where there is almost no gravity, engineers can just attach a small rocket on the side of the huge one. When they fire the rocket Newton’s law of inertia starts up. As there is no air or wind friction in space, the rocket continues until it hits the moon. Mission accomplished!
