Front

Define kinetic energy.

Back

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

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally, while non-renewable sources are finite and deplete over time.

Front

What is the role of a turbine in a nuclear power plant?

Back

A turbine converts steam energy into mechanical energy to generate electricity.
