Vocabulary
The ability to do work
What is energy
The main source of energy for our planet
What is the sun
Measurement from crest to crest of trough to trough.
What is wavelength
Heat always moves from a __________ object to a __________ object.
What is warmer to cooler
What state of matter does sound travel through the best and why
What is solids because its particles are close to together
The difference between kinetic and potential energy
What is Kinetic Energy is the energy of motion while Potential Energy is Stored energy
What are the two factors that affect kinetic energy
What is mass and speed
The height of a wave
What is amplitude
A material that conducts thermal energy poorly
What is an insulator
What is a Wave
What is a disturbance that transports energy through matter or space
All energy can be classified into two general types:
What is potential energy and Kinetic energy
Two factors that affect potential energy
What is mass and height
The number of waves that passes a given point in 1 sec.
What is frequency
When heat energy is transferred by electromagnetic waves or rays
What is Radiation
The relationship between wavelength and frequency.
What is the shorter the wavelength the greater the frequency or What is the longer the wavelength the lower the frequency
Units of Energy
What is Joules
Two types of potential energy
What are gravitational and elastic potential
When a wave interacts with an object what three things can occur
What is reflection, refraction, and absorption
When heat (energy) is transferred by particle collisions in a material is called this (think about a metal ladle in a in boiling water - direct contact)
What is Conduction
Why can't sound exist in space
What is space is a vacuum and sound waves need a medium to travel through
The Law of Conservation of Energy States -
What is energy is never created nor destroyed but transferred from one form to another.
List 3 types of energy and give an example for each
Answers will vary
What two properties of a wave make up color?
What is wavelength and frequency
The transfer of heat energy through a fluid (Air or Liquid)
What is Convection
The difference between a longitudinal wave and a transverse wave, and provide an example of each type of wave.
A longitudinal wave, the particles of the medium vibrate parallel to the direction of the wave propagation. Ex (Sound Waves)
A transverse wave, the particles of the medium vibrate perpendicular to the direction of the wave. Ex (Light Waves)
