Energy - Science 8

Front

What does gravitational potential energy depend on?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

Which point has the greatest kinetic energy?

Back

Point X has the greatest kinetic energy.

Front

What kind of energy is represented by heat?

Back

Thermal energy is the energy represented by heat.

Front

Is geothermal power a renewable or nonrenewable energy resource?

Back

Geothermal power is a renewable energy resource.

Front

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

Back

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

Front

Define kinetic energy.

Back

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

Front

Define potential energy.

Back

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

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the difference between renewable and nonrenewable energy resources?

Back

Renewable energy resources can be replenished naturally, while nonrenewable resources cannot be replaced once used.

Front

Give an example of a renewable energy source.

Back

Solar energy is an example of a renewable energy source.
