Types of Energy

Front

What is the definition of 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 process do plants use to convert solar energy into chemical energy?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, particularly from the nucleus of an atom. It is a form of potential energy.

Front

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a big hill on a roller coaster, where the height is greatest.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and velocity of an object.

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 type of energy is associated with the motion of particles in a substance?

Back

Thermal energy is associated with the motion of particles in a substance, which is related to temperature.

Front

What is mechanical energy?

Back

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

Front

How does gravitational potential energy differ from elastic potential energy?

Back

Gravitational potential energy is energy stored due to an object's height above the ground, while elastic potential energy is stored in objects that can be stretched or compressed, like springs.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.
