NEWTONS FIRST LAW

 Newton’s Second Law of Motion introduces one of the most important fundamental concepts in science: mass. Sir Isaac Newton used the word “mass” as a synonym for “quantity of

matter.” Today, we more precisely define mass as a “measure of the inertia of a body.” The more mass an object has the more difficult it is to change its state of motion, whether i t is at rest or moving in a straight line at a constant speed. Think of i t this way: An elephant has more inertia than a mouse. It is much harder to push an elephant across a floor than it is a

mouse, and much harder to stop the elephant once it is moving. Therefore, by definition, an elephant has more mass than a mouse Newton’s Second Law takes up where the First Law ends. The First Law describes inertia: A body will not change its existing state of motion without a net force acting on that body. In

other words, without an outside force a body will remain still if stil l, or, if moving, keep moving in the same direction at a constant speed.re mass than a mouse.

In the first diagram two people are putting force to push the wagon and in the second diagram it is only one

person.

We are going to get a ballon with mentos in it and attack it to the bottle of soda to see how big the ballon gets
