Energy Screams

How does the passage define a roller coaster?

• the application of kinetic energy to generate massive amounts of potential energy in order to create an exciting experience

• an amusement park ride that does not rely on gravity

• a thrilling ride that almost everyone enjoys

• the application of potential energy to generate massive amounts of kinetic energy in order to create an exciting experience

"At the top of the first and tallest hill, your potential energy is at its highest it will ever be on this ride. As you begin to descend, your potential energy decreases until it's all gone at the bottom of the hill."

"At the bottom of the first hill, your kinetic energy is at its highest point. You're going as fast as you'll ever go on this roller coaster ride."

Based on this evidence, what conclusion can be made

• A roller coaster is fastest at the front of the train.

• The shorter the hill the roller coaster climbs, the greater its kinetic energy.

• Potential energy is converted to kinetic energy as the roller coaster goes down the hill.

• No conclusion can be made from this evidence.

Why is it necessary for a roller coaster to go up a hill?

• The potential energy of the roller coaster increases as the coaster goes up a hill and can be converted to kinetic energy. This kinetic energy allows the coaster to do different things

• The kinetic energy of the roller coaster increases as the coaster goes up a hill and can be converted to potential energy. The potential energy allows the roller coaster to do different things.

• The kinetic energy and potential energy increases as the coaster goes up a hill. This increase in kinetic and potential energy allows the roller coaster to do different things.

• The kinetic energy and potential energy decrease as the coaster goes up a hill. This decrease in kinetic energy allows the coaster to do different things.

Why do roller coaster designers include a second hill on the ride? (Mark two answers)

• to build up more potential energy that can be converted to kinetic energy as the roller coaster goes down the hill.

• to make the ride longer

• to use more material

• to make it look scarier

In a loop-the-loop section of a roller coaster, kinetic energy is the highest when

• the coaster is at the top of the loop

• the coaster is at the bottom of the loop

• the coaster is in the middle of the loop
