Forms of energy and Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

True or False: Energy can be created or destroyed.

Back

False. Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object at the top of a hill.

Front

Where is potential energy the highest?

Back

At the top of a hill.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

True or False: Nuclear fission is the process of splitting a large nucleus into smaller nuclei.

Back

True.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two small nuclei to form a larger nucleus, releasing energy.

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.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.
