Energy Final

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 happens to chemical bonds when a matchstick is lit?

Back

The chemical bonds in the match are broken, allowing the stored chemical energy to be released as heat and light.

Front

Which of the following is not a source of chemical energy?

Back

The Sun is not a source of chemical energy; it is a source of radiant energy.

Front

What does work transfer?

Back

Work transfers energy from one system to another.

Front

What is heat?

Back

Heat is energy that is transferred between objects due to their temperature differences.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its 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 chemical energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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