Force- is a push or a pull
Energy- is to be able to do work and make a change
Potential energy- Is stored energy. It is called potential because it has the potential to be converted into other forms of energy
Kinetic energy- is the extra energy an object possesses to use its motion once it has accelerated. Kinetic energy is the energy of motion
Work- ability to make a change, object +force +motion =work.
Types of energy- Light, Sound, Heat, Potential, Kinetic.

Spectrum of light- sunlight is made up of many different colors of light but all together they look white to our eyes another name of light is separated is SPECTRUM.
Refract- when light passes through a prism it gets refracted or bent.
Additive color mixing- mixing light beams because each beam of light adds color to the mixture which is why light on the screen from the combined beams is brighter then the light from either beam itself.
Subtractive color mixing- The color of a object, pigment make objects appear colored by absorbing or swallowing up most of the colors of light that hit then and reflecting or bouncing back the rest.

Engineering- Using math and science to solve a problem.
