Types of Energy
100

Is a light wave transverse or longitudinal?

It is transverse.

100

Is a sound wave transverse or longitudinal?

It is longitudinal.

100

True or false: energy cannot be created or destroyed.

True, it can only be transformed or transferred.

100

The name of the force exerted by magnets when they attract each other.

What is magnetism?

100

This type of energy comes from an object's movement.

Kinetic energy.

200

What does wavelength correlate to on the light spectrum?

Reds have longer wavelengths, and violets have shorter wavelengths.

200

This causes sound to amplify.

What is constructive interference?

200

When this type of wave is absorbed, it usually turns into thermal (heat) energy.

What happens when a light wave is absorbed?

200

True or false: when electrons spin in different directions, it creates a magnetic field.

False, a magnetic field is created when electrons spin in the same direction.

200

This type of energy comes from an object's position, shape, or chemistry.

Potential energy.

300

What does amplitude correlate to on the light spectrum?

Amplitude determines how bright something is. The brighter, the greater amplitude.

300

This causes sound to reduce.

What is destructive interference?

300

How does the Doppler Effect affect sound waves?

When soundwaves are closer, they appear to have a higher pitch and may sound louder.

300

What is electricity caused by?

The separation and movement of charged particles continues through a conductor and complete circuit.

300

This is the unit for energy.

What is a joule?

400

What is frequency and what is it measured in?

Frequency is the # of waves produced in a time period, measured in waves/sec (Hz).

400

This type of wavelength causes something to sound deeper/have a lower pitch.

How does a longer wavelength correlate to pitch?

400

How does the Doppler Effect affect light waves?

"Redshift" signals when objects are traveling further away, while "blueshift signals when objects are traveling closer. (all space related)

400

This type of field occurs when electric currents create a magnetic field. This also causes the aurora borealis.

What is an electromagnetic field?

400

Is mechanical energy potential or kinetic?

Neither, it is the sum of gravitational potential energy and kinetic energy.

500

This happens when light reflects, refracts, or transmits through a bubble.

When does constructive/destructive interference happen?

500

Does sound travel faster through denser materials?

Yes, it does.

500

This transformation happens when gas is put in a car.

Chemical -> electrical.

500

What's the difference between a direct current and an alternating current?

Direct currents always go in one direction, while alternating currents might sometimes switch direction.

500

What does each letter in MECHNLEGS stand for?

M-mechanical (gpe+k) 

E-electrical (k)

C-chemical (p)

H-heat (thermal) (k)

N-nuclear (p)

L-light (radiant) (k)

E-elastic (p)

G-gravitational (p)

S-sound (k)
