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.
NEWTON’S SECOND LAW
In the first diagram two people are putting force to push the wagon and in the second diagram it is only one
person.
NEWTON’S SECOND LAW
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
NEWTONS THIRD LAW
1.No forces applied to ballons .2.Both push on ballons.
