Energy Transformations

Front

What is kinetic energy and what factors affect it?

Back

Kinetic energy is the energy an object possesses due to its motion. It is affected by both the mass and speed of the object.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What type of energy is produced when a cell phone rings?

Back

Sound energy is produced when a cell phone rings.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.

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 law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a battery converting chemical energy into electrical energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

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 (e.g., fossil fuels) cannot be replaced once used.

Front

What is sound energy?

Back

Sound energy is a form of energy that is associated with the vibration of matter.
