Energy Flashcard

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a stretched bowstring has potential energy because it can do work when released.

Front

How is kinetic energy defined?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

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 an example of energy transformation?

Back

An example of energy transformation is when a rubber band is stretched (potential energy) and then released, converting that energy into kinetic energy as it snaps back.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity. The formula is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

How does friction affect energy transformation?

Back

Friction converts kinetic energy into thermal energy, often resulting in heat and sound.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a book on a shelf. It has potential energy due to its height above the ground.
