CUA Energy 2024

Front

What happens to kinetic energy (KE) and potential energy (PE) when a roller coaster rolls up a hill?

Back

KE decreases and PE increases.

Front

At the highest point of a roller coaster, what type of energy does the roller coaster have?

Back

The roller coaster has all potential energy.

Front

What is the unit of measurement for speed?

Back

m / s (meters per second)

Front

When a pendulum ball is at its lowest point, what can be said about its speed?

Back

This is the point the pendulum is fastest.

Front

Where does a roller coaster have the greatest velocity?

Back

At point X.

Front

Define kinetic energy (KE).

Back

The energy that an object possesses due to its motion.

Front

Define potential energy (PE).

Back

The energy stored in an object due to its position or height.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

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

Front

Explain the law of conservation of energy.

Back

Energy cannot be created or destroyed, only transformed from one form to another.
