At what point does the roller coaster have the highest amount of potential energy?
At the bottom of the first hill.
At the top of the third hill.
At the end of the ride.
At the top of the first hill.
At what point of the ride have the highest kinetic energy?
At the lowest point of the ride.
At the highest point in the ride.
On the middle hill of the ride.
Roller coasters do not exhibit kinetic energy.
Stored energy is also known as...
Kinetic energy
Thermal energy
Potential energy
This is a trick question
A group of students conducted an investigation to collect data on how much potential energy an object has as it moves farther and farther from Earth's surface. To measure this students dropped a marble from different heights onto clay and measured the crater left by the marble by filling it with drops of water. Their results are shown in the picture. What is the independent variable in this experiment?
mass of the marble
height
drops of water (volume of crater)
diameter of marble

A group of students conducted an investigation to collect data on how much potential energy an object has as it moves farther and farther from Earth's surface. To measure this students dropped a marble from different heights onto clay and measured the crater left by the marble by filling it with drops of water. Their results are shown in the picture. What is the relationship between the height of the drop and crater depth.
On average the higher the ball was dropped from the deeper the crater is.
On average the lower the ball was dropped from the deeper the crater is.
On average the higher the ball was dropped from the shallower the crater is.
There is no relationship between release hight and crater depth.

What would a graph of this data look like?
A demonstration helps students understand a principle of roller coaster design.
Which answer choice correctly describes the ball’s kinetic and potential energy?
The ball has more potential energy at position X than at position Z.
The ball has more kinetic energy at position Y than at position W.
The potential energy and kinetic energy of the ball are equal at position X.
The potential energy and kinetic energy of the ball are greatest at position Z.
