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.

Magnet- is an object that attracts certain objects toward it

Magnetism- is an attractive force

Law of magnetic attraction- like poles repel, unlike poles attract

South pole

North

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.

Sound energy- is energy you can hear.

Vibration- means the object moves quickly back and forth.

Sound waves- when a wave carries energy from on place to another.

Frequency- number of waves in a sound per second.

Volume- how loud or how soft a sound is.

Technology- Anything that people create to solve a problem.

Engineering Design Process- Ask questions, imagine solutions, plane and create, design and prove it.

Engineering- Using math and science to solve a problem.
