Energy Flashcard 1-2 Relearning

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop. It often generates heat.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

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 from one form to another.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on an object's position.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, processes that involve the splitting or combining of atomic nuclei.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

How is energy transformed when rubbing hands together?

Back

When you rub your hands together, kinetic energy from the motion is transformed into thermal energy, warming your hands.

Front

What is an example of energy transformation in a bike?

Back

In a bike, kinetic energy from pedaling is transformed into electrical energy when using a generator.
