Unit 1
a system in which both matter and energy can be exchanged with its surroundings.
Open System
is the ability to do work (force in a direction)
Energy
states that energy can neither be created nor destroyed - only converted from one form of energy to another
Law of Conservation of energy
is a rhythmic disturbance that transfers energy through a medium or a vacuum.
Wave
ALL waves carry ENERGY, but not what?
Matter
Is energy of vibrating materials or air molecules.
Sound
is energy that is stored in the bonds holding atoms together.
Chemical energy
is the energy that is stored and held in readiness to work
Potential energy
is the matter through which a wave can travel. It can be a solid, liquid, or gas.
Medium
Waves that REQUIRE a medium for motion. Can be transverse or longitudinal.
Mechanical
is energy released when atoms split apart or join together.
Nuclear Energy
John started to run to the fruit isle because the store was about to close. He instantly stop to get a pear and two apples. He then started to walk to the register. The manager decided to close the store 2 minutes earlier, so he started to run.
Kinetic, potential, kinetic, kinetic
Waves that DO NOT require a medium for motion. Can travel through empty space/vacuum.
Electromagnetic Waves
A type of wave that moves the medium at a right angle (perpendicular) to the direction in which the wave travels
Transverse waves
a negative relationship where as one variable increases, the other decreases.
Inverse relationship
is stored energy that exists based on the position of an object. The higher an object is, the greater its gravitational potential energy.
Gravitational Energy
the amount of heat required to raise the temperature of 1g of a substance by 1 0C.
Specific Heat
Longitudinal Wave
(the location where the particles are closest together on a longitudinal wave)
Compression
When a wave bends as it passes through one medium into another.
Refraction
As amplitude increases, the energy of the wave
increases
When fluids are heated particles have more energy, move faster & spread out.
Convection
Particles vibrate faster when they have more thermal energy. They collide into other particles, which gives those particles more thermal energy.
Conduction
What are the four wave interactions?
Reflection, refraction, diffraction, interference.
This is a Longitudinal wave
(The location where the particles are farthest apart on a longitudinal wave)
Rarefaction
Out of blue, green, violet, yellow, orange and red. Which color has the shortest wavelength.
Violet
