Roller Coaster Project - Checkpoint #1

Front

At which position is the kinetic energy the greatest?

Back

Position 5 has the greatest kinetic energy as it is the lowest point in the roller coaster where the speed is highest.

Front

At which point in the roller coaster's journey is its potential energy the greatest?

Back

Point Z has the greatest potential energy as it is the highest point in the roller coaster.

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy due to motion.

Front

The faster an object moves, the ________ kinetic energy it has.

Back

The faster an object moves, the more kinetic energy it has.

Front

__________ is stored energy.

Back

Potential energy is stored energy.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to potential energy as a roller coaster descends?

Back

As a roller coaster descends, potential energy decreases while kinetic energy increases.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What type of energy is present at the top of a roller coaster?

Back

At the top of a roller coaster, potential energy is at its maximum.
