### We will look at the science that is seen at a Theme Park like Fiesta Texas.

Then, we will look at the Math that relates to the science that we have seen.

### But before we do that…

We need a little background information.

Introducing Isaac Newton

### Conservation of Energy

Potential Energy = Kinetic Energy

• An object has the Potential to do energy.

• An object has Kinetic

• Energy when it is in

• motion

### Potential Energy

• At the top of the hill, the roller coaster has its greatest potential energy.

• As it starts down the

• hill, potential energy

• begins to decrease.

### Kinetic Energy

• Again, is what potential energy changes into because the roller coaster is moving.

• At the bottom of the hill the roller coaster is going its fastest, so the kinetic energy is its greatest.

### You See…

Energy is always conserved!

• At any given point along the roller coaster you will have….

• E=PE+KE

• PE = mgh & KE = ½ mv*v

• Hence you get:

E = mgh + ½ mv*v

m = mass

g = gravity

v = velocity

### In Review…

• At the top of the hill the roller coaster has its greatest potential energy. {KE = 0}

• As it begins down the hill, potential energy decreases as kinetic energy increases.

• Then at the bottom of the hill, potential energy is at its lowest point while kinetic energy is at its greatest. {PE = 0}
