FLASHCARD QUESTION
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.
2.
FLASHCARD QUESTION
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.
3.
FLASHCARD QUESTION
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.
4.
FLASHCARD QUESTION
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.

FLASHCARD QUESTION
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.
6.
FLASHCARD QUESTION
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.
7.
FLASHCARD QUESTION
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.
