What is mass the same as?

Inertia

100

What is the symbol for the spring constant?

k

100
What direction does an electric field go?
positive to negative
100

What is the difference between longitudinal and transverse waves?

In longitudinal waves the vibratory disturbance is parallel to the energy transfer, whereas in transverse waves it's perpendicular
100
What does the strong force act on?

nucleons (protons and neutrons)

200

In a collision, what is conserved?

Momentum

200

What does an ideal mechanical system not account for?

friction/air resistance

200

What three things do you need to form a current?

a magnet, a wire, and motion

200

What type of wave can travel through a vaccum?

Light waves; sound waves rely on a medium to travel

200

When an electron goes up a level, is energy absorbed or emitted?

absorbed

300

How many degrees between vectors gives the biggest resultant?

0 degrees

300

Total energy in a system is equal to ... ?

The sum of potential, kinetic, and thermal energy

300

What type of wires are the best conductors?

cold, fat, and short wires

300
Frequency is the reciprocal of which property?

period

300

What color do absorption spectral lines appear to be?

black

400

When an object accelerates upwards in an elevator, is its normal force bigger or smaller than its weight (mg)?

Bigger

400

What are the different units for energy?

Joules and eV

400

How does the strength of the field change as you move between parallel plates?

It doesn't change, the field strength between parallel plates is equal.
400

What are the three things that happen when a wave hits an interphase?

Part is reflected, part is absorbed, and part is transmuted

400

How many frequencies can be emitted from 5 to 1?

10

500

What is the force of gravity between 2 1kg objects that are 1m apart?

Fg=6.67x10-11 N

500

What is a non-conservative force? Give an example

One that reduces the mechanical energy of a system, ie friction

500

What is a capacitator?

A device that can hold charge indefinitely then quickly releases it

500
How are standing waves formed?
When two waves with the exact same amplitude and frequency travel in opposite directions.
500

What happens to the excess energy left over after an atom is ionized?

It is transformed into the kinetic energy of the electron
