What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a combination of two or more substances that remain distinct and can be easily separated, such as gravel, sand, and clay in water.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the components are uniformly distributed and cannot be easily distinguished, like saltwater.

Front

What is radiant energy?

Back

Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as light.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is a chemical change?

Back

A chemical change is a process where substances combine or break apart to form new substances with different properties, such as when two liquids in a glow stick mix.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout, such as distilled water.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

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 role of plants in energy transformation?

Back

Plants convert radiant energy from the sun into chemical energy through the process of photosynthesis.
