Forms of Energy
... • Radiant Energy is light energy given off in the form of waves and particles (called photons) (see it) • Most light energy is not visible to human eyes; radiant energy is a part of the electromagnetic spectrum. (see it) • The Sun is the Earth’s main source of radiant energy ...

Work and the Work-Energy Principle
... • Work is what is accomplished by a force acting on an object (i.e., movement in the direction of that particular force) • Work is a scalar quantity - no direction • It can, however, be either positive or negative. Positive if the object moves at least partly in the direction of the force. Negative ...
