Work is an object with force and motion. Force is a push or pull Energy is what makes things change Potential energy is stored energy. It is called potential energy because it has the potential to be converted into other forms of energy. Kinetic energy is the extra energy an objects possesses to use motion once it has accelarated. Kinetic energy is the energy of motion.
A magnet is an object that attracts certain other objects toward it. Magnetism is an attractive force Like poles attract and unlike poles repel.
Additive color mixing is mixing light beams because each beam of light adds its color to the mixture which is why light on the screen from the combined beams is brighter than the light from either beam by it self. Subtractive color mixing is the color of an object. Pigment makes objects appear colored by absorbing or swallowing up most of the colors of light that it them and reflecting or bouncing back the rest. Prism solid transparent object that redirects and separates light rays so you can see the spectrum of Roy g biv. Roy g biv stands for red, orange, yellow, green, blue, indigo, violet. Refract is when light passes through a prism it gets refracted or bent.
normal smaller bigger and upside down What does a concave mirror reflect back.
correct The light rays converge and cross so thats why it appears bigger and upside down.
What does a convex mirror reflect back. An image that appears smaller An image that appears normal An image that appears bigger and upside down
when the mirrors light rays diverge and spread apart the image becomes smaller.
waterSolid objectsgas What does sound travel best through?
Sound travels at through solid objects at 4500per a second
Sound energy is energy you can hear. Vibrations are back and forth movements. Sound waves carry energy from one place to another. Frequency is how high or low the sound is. Volume is the loudness of a sound or the softness BoneEar drum Auditory Nerve anvil Hammer Cochlea
Engineering is using math and science to solve problems Technology is anything that people make to solve a problem` Engineering design process is asking questoins, imagne, solutions, plan and create your design and improve it
