Ocean Powered - Lesson 2

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What two factors determine the amount of energy an object has?

Back

The amount of energy an object has is determined by its mass and speed.

Front

What happens to kinetic energy as the mass of an object increases?

Back

As the mass of an object increases, its kinetic energy increases.

Front

Why is Saltstraumen a good location for an Ocean Energy Converter (OEC) device?

Back

Saltstraumen is a good location for an OEC device because of its strong waves.

Front

What is the relationship between the speed of an object and its energy?

Back

As the speed of an object increases, its energy increases.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

How does the speed of a pinball affect its kinetic energy?

Back

The speed of a pinball affects its kinetic energy; as speed increases, kinetic energy increases.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What role do waves play in ocean energy conversion?

Back

Waves provide the kinetic energy needed to generate electricity in ocean energy converters.
