chemical

What type of energy is stored in batteries?

Work is a measure of how much energy a force transfers.

Which describes energy and work?

thermal energy

Which form of energy is due to the motion of an object's particles?

A person walking up a hill

Which of these is an example of the conversion of kinetic energy into gravitational potential energy?

Energy cannot be created or destroyed, but it can be transformed and transferred.

Which statement is true of energy?

kinetic energy

_ is energy in motion

nuclear energy

_is the potential energy stored in the nucleus of an atom. Ex: The energy given off by the sun.

work

f x d / The unit of work is joules (J).

pontenial energy

is energy that is stored.

sound energy

is kinetic energy caused by the vibration of particles in a medium, such as steel, water or air

electrical energy

is kinetic energy of moving electrical charges. Electrical energy can occur in nature in the form of lightning and smaller static electrical shocks.

Energy

is the ability to do work or to cause changes in matter.

Electromagnetic energy

is the kinetic energy of electromagnetic waves, which include visible light, x-rays and microwaves

chemical energy

is the potential energy stored in the chemical bonds of substances. Ex: batteries, fuels and matches

elastic energy

is the potential energy stored in the chemical bonds of substances. Ex: batteries, fuels and matches

mechanical energy

is the sum of the object's kinetic and potential energy.

thermal energy

is the total kinetic energy of all the particles that make up an object.

Work

is the transfer of energy to an object by a force that causes the object to move in the direction of that force.

Gravitational potential energy

.. Which term describes the energy that is stored due to the height of an object about the ground?
