SCI 126 1.5 Energy Transfer and Transformation

Energy

is defined as the capacity to do work or cause change, measured in joules (J).

Kinetic Energy

the energy of motion; can be measured from the work done to put an object in motion, from the mass and velocity of the object while in motion

Potential Energy

stored energy due to position; energy associated with changes in position

Gravitational Potential Energy

stored energy associated with the position of an object and height in a gravitational field

Elastic Potential Energy

potential energy in a system that depends on the position or shape of an elastic object

thermal energy

is the total energy of all the microscopic particles in a substance due to their motion and interactions.

Acoustical Energy

is the mechanical energy carried by sound waves as they travel through a medium such as air, water, or solids

chemical energy

potential energy stored in chemical bonds

electromagnetic radiation

is energy that travels through space in the form of electromagnetic waves

conservation of energy

Energy cannot be created or destroyed

energy transfer

Movement of energy from one place or object to another

energy transformation

A change from one form of energy to another

weight

A measure of the force of gravity on an object
