Newton's Law'sAllie Magas

Isaac Newton was an English mathematician and an astronomer. He defined the relationship between force and mass. His ideas are also known as the scientific laws.

His First Law also known as Law of Inertia, the tendency of an object to resist a change in its motion. Another way to put this is an object at rest stays at rest, an object at motion will stay in motion unless acted upon by an unbalanced force.

Newton's Second Law can be stated as: The mass of an object affects the acceleration. The more mass the more amount of force needed to accelerate the object. The formula for the second law is Force=Mass times Acceleration.

The Third Law is for every action, there is an equal and opposite reaction. When two objects interact their forces act upon each other. An easier way to explain this is when an object pushes another object it pushes back in the opposite direction equally as hard.

Here is the perfect example of action reaction. The rockets action is to push down on the ground with the force of the engines, the reaction is that the ground pushes the rocket upwards with an equal amount force.

This video shows the Three Laws of Motion in the sport of soccer. Here we see the First Law as the ball gets kicked it was at rest. Then the unbalanced force, my foot, kicked it and put the ball in motion. The Second Law of motion is shown in the ball. The amount of mass in the ball predicted how much force I needed to kick the ball. If the ball had more mass than I would need more force to get the ball in the air. When I kicked the ball all the force I put into the ball repelled back into my foot. This explains and shows an action to reaction example and the 3rd and final law of motion.
