Front

What is the energy of the movement of objects called?

Back

Motion energy

Front

What does efficiency measure?

Back

Efficiency measures how much work is output versus how much work is input.

Front

What is the standard unit of energy?

Back

Joule

Front

What type of energy is stored in the tension of objects from stretching and compressing?

Back

Elastic potential energy

Front

What is the ratio of work output to work input measured as a percent called?

Back

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

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

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources cannot (e.g., fossil fuels).

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.
