PRESENTATION OUTLINE
ACTION AND REACTION
There can never be a single isolated force if you hold something gravity pulls it (force number one) and you hold it so it doesn’t fall (force number two)
NEXT EXAMPLE
Think of sitting in a chair gravity uses a downward force and the chair pushes an upward force
(two forces)
LAST EXAMPLE
Think of a car hitting a wall if it hits the wall the wall puts a force to stop the car instead of it just keeping on rolling but the car puts a force to hit the wall so there are two forces
Action and reaction
IF THERE WERE AN ISOLATED FORCE
If there was an isolated force we would go through the earth and rock to the center of the earth and die by lava so the force of the dirt,rock and other masses we stay on the surface. So gravity pulling us down (force number one) earth, dirt and rocks holding us up (force number two)
THERE ARE TWO MORE TYPES OF ENERGY YOU LEARNED THE FIRST ONE
When you go up the roller coaster it makes an energy called potential energy and when it goes down it makes a thing called kinetic energy.
