Forms of Energy

Front

What is mechanical energy?

Back

Mechanical energy is the energy of motion or moving parts, which can be observed in objects that are in motion.

Front

What is chemical energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, felt as heat, and is related to the kinetic energy of particles.

Front

How does mechanical energy differ from thermal energy?

Back

Mechanical energy is associated with the motion of objects, while thermal energy is related to the temperature and heat of a substance.

Front

What are some examples of mechanical energy?

Back

Examples of mechanical energy include a moving car, a spinning fan, and a flowing river.

Front

What are some examples of chemical energy?

Back

Examples of chemical energy include the energy stored in food, batteries, and fuels like gasoline.

Front

What are some examples of thermal energy?

Back

Examples of thermal energy include the heat from a stove, the warmth of the sun, and the heat produced by friction.

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

How can energy be transformed from one form to another?

Back

Energy can be transformed through various processes, such as combustion (chemical to thermal), a generator (mechanical to electrical), or a battery (chemical to electrical).

Front

What is kinetic energy?

Back

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