QuestionAnswer
Temprature a measure of the average kinetic energy of the particles in an object.
Thermal expansion The increase in volume of a subtance due to an increase in temprature.
Absoolute zero The lowest tempature on the kelvin scale is 0 k which is called?
Heat Is the transfer of energy between objects that have different tempratures.
Thermal energy Is the total energy of the particles that make up a substance.
Conduction is the tranfer of thernmal energy from one substance to another through direct conact.
conducters substances that conduct thermal energy very well are called?
insulators subsances that dont conduct thermal energy well.
convection the transfer of thermal energy useing a liquid or gas.
wave is any disturbance that transmits energy through matter or space.
medium is a substance through which waves can travel.
longitudinal wave the particles of the medium vibrate back and forth along the path that the wave travels.
amplitude the maximum distance the wave vibrates from its rest position.
wavelength is the distancebetween any two adjacent crests or compressions in a series of waves.
frequency the number of waves produced in a certain amount of time.
wave speed the speed at which a wave travels.
reflection when a wave bounces back after stricking a barrier.
refraction the bending of a wave as it passes at an angle from one medium to another.
interference the results of two or more waves overlapping.
standing wave a wave that forms a stationary pattern in which portions of the wave are at the rest position due to total destructive interference and other portions have a large amplitude due to constructive interference.
resonance when an object vibrating at or near the resonant frequency of a second object causes second object to vibrate.
How energy transfers through a medium an object vibrates and passes energy to a particle next to it. The second particle
How sound waves work particles travel through a medium by vibration. If there are no particles to vibrate, no sound is possible.
How ocean waves transfer energy particles vibrating throughout the water
Electromagnetic waves waves that do not require a medium
Examples of things that operate using electromagnetic waves microwaves, ovens, TVs, radio signals and x rays
How can waves be classified based on the direction in which the particles of a medium vibrate compared to the direction in which the waves travel.
How do transverse waves move particles vibrate with and up and down motion
How do longitudinal waves move particles of the medium vibrate back and forth along the path that the wave travels.
Wave speed formula Wave Speed
Wave Speed the bending of waves around a barrier or through an opening
Interference the result of two or more waves overlapping

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
