Potential energy is energy that is

According to the law of conservation of energy, which statement is possible?

• The amount of energy available in the universe never changes.

• Energy is destroyed during an energy transfer.

• Energy is created during the formation of chemical bonds

• The total amount of energy in a closed system decreases.

Sound and X-rays are forms of energy that

• Are carried by waves.

• Travel in electric currents.

• Are sensed by the human ear.

• Are part of the particles of matter.

Which type of potential energy is in object that is above ground?

• Radiant potential energy

• Kinetic potential energy

• Mechanical potential energy

• Gravitational potential energy

A movement of energy from one object to another without a change in the form of energy is called

• Energy transfer.

• Energy reversal.

• Energy transformation.

• Chemical source

Which is a renewable energy resource that is used to produce electricity?

• Biomass

• Coal

• Natural gas

• petroleum

Thermal energy is

• Produced during energy transformations only.

• Not produced by energy transfers or energy transformations.

• Produced during energy transfers and energy transformations

• Produced during energy transfers but not during energy transformations.

All energy transformations and energy transfers result in the formation of some

• Sound energy

• Thermal energy

• Radiant energy

• Gravitational energy

Which describes the sum of potential energy and kinetic energy of objects or systems?

• Nuclear energy and electric energy

• Nuclear energy and mechanical energy

• Thermal energy and electric energy
