6.3.3 Other forms of energy

Front

What type of energy does the body receive after eating an apple?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food. When we eat, our body converts this energy into usable forms.

Front

What is another name for heat?

Back

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

Front

What does it mean if an object is very hot?

Back

An object that is very hot has a lot of thermal energy, which means its particles are moving rapidly.

Front

What must be true about an object for it to have kinetic energy?

Back

An object must be moving to have kinetic energy, which is the energy of motion.

Front

What process do nuclear power plants use to create electricity?

Back

Nuclear power plants use fission, which is the splitting of atomic nuclei to release energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers our homes and devices.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a heavy nucleus into smaller nuclei, while fusion is the combining of light nuclei to form a heavier nucleus.

Front

What is an example of chemical energy?

Back

An example of chemical energy is the energy stored in food, batteries, and fuels like gasoline.
