Work, Energy. Power. and Simple Machines
This states that the net work done on an object is equal to its change in kinetic energy.
What is the Work Energy System?
Another term for Stored energy.
What is potential energy?
The highest point in a wave
What is Crest
This is the reason there is no sound in space.
What is a lack of medium (air)?
The seven colours visible light is made up of.
What is red, orange, yellow, green, blue, indigo, and violet?
Having the ability to produce a change in itself or its surroundings
What is Energy?
The energy of motion.
What is kinetic energy?
A measure of the distance a wave travels in an amount of time.
What is speed
Sound intensity is measured in this unit.
What is decibels?
Waves that can travel through matter or empty space where matter is not present.
What is Electromagnetic Waves
A system that simply reverses the direction of a force.
What is a pully system?
The common SI unit used for measuring energy.
What is a Joule?
A measure of the distance from the crest on one wave to the crest on the very next wave.
What is Wavelength
Interference in which multiple waves combine and have a greater amplitude.
What is constructive interference
The complete reflection of light at the boundary of two transparent media
What is total internal refraction?
The ratio of output force to input force for a machine
What is Mechanical Advantage?
The law that states that the sum of potential and kinetic energy in a body is constant.
A measure of how many waves pass a point in a certain amount of time.
What is Frequency
Periodic changes of loud and soft due to sound intensity is called this.
What are beats?
The failure of a lens to create an accurate image
what is spherical aberrations?
A simple Machine, consisting of a bar that rotates around a fixed point
What is a lever?
A 12 kg projectile leaves a cannon at a velocity of 200 m/s. This is the amount of kinetic energy of the projectile.
What is 240,000 joules?
The bending of waves caused by a change in their speed as they pass from one medium to another
What is Refraction
The increase or decrease of the frequency of a sound heard by an observer due to relative motion between listener and source.
What is doppler effect?
This color is NOT an additive primary color
What is Yellow?
