What is thermal energy?
Atoms or particles that collide, creating heat.
What is Sound energy?
Particles vibrating creating area of pressure.
What is light energy?
A form of Electromagnetic radiation, consisting of photons.
What is the energy input and what is produced? An avalanche rolls down a steep mountain.
Potential energy to kinetic energy.
What is Potential Energy?
Stored energy.
What does conductive mean?
Heat transfer by direct contact.
How do we increase the pitch?
A. Increase Frequency
B. Increase amplitude
C. Increase wavelength
Increase the frequency.
What color light has all the colors of the rainbow?
White light
What is the energy input and what is produced? A car battery causes the headlights to shine.
Electrical energy to light energy.
What is Kinetic Energy?
Energy of Motion.
What does convection mean?
Heat transfer by liquid or gas particles moving. Heat rises cool falls.
Which type of matter does sound travel through the fastest?
Solid matter.
What is the smallest unit of light?
A photon.
What is the energy input and what is produced? A candle burns and lights up the room.
Chemical energy to light energy.
Which of these is a type of Kinetic Energy?
A. Chemical energy
B. Gravitational energy
C. Sound energy
D. Elastic energy
C. Sound energy
What is thermal radiation?
Heat transfer by electromagnetic waves.
When you turn up the sound on your speakers/headphones, what part of the wave are you affecting?
A. Crest
B. Trough
C. Frequency
D. wavelength
E. Amplitude
The amplitude (how tall the wave is)
Light waves travel in a straight line, but wiggles as the travel. What do we call this type of wave?
A Transverse wave.
If we think of a smartphone, the input is electrical energy. What would be all of the possible energy outcomes?
Thermal energy (phone gets hot), Sound energy (makes noise), Light energy (screen makes light)
Which would have more Potential Energy, A Skier who weighs 150 pounds on a hill, or a Snowboarder who weighs 250 pounds on the same hill?
A Snowboarder who weighs 250 pounds.
If you heat up an object really hot, what happens?
Sound waves travel in a straight line, but go in and out/ back and forth as it travels. what do we call this type of wave?
A Longitudinal wave.
Why is the sky blue?
When sunlight hits the earths atmosphere it scatters, blue light scatters more so we see the sky as blue.
If we think of a car, the input is chemical energy (gasoline). What would be all of the possible energy outcomes?
Light energy (headlights), Kinetic energy (the car moving), Thermal energy (heat), Sound energy (engine revving).
