100
This is the formula for calculating momentum.
momentum = mass multiplied by velocity (p = mv)
100
A pan heating up on a stove burner is example of this type of heat transfer.
Conduction (because the pan and stove burner are touching)
100
A wave of any kind is simply transferring this from one place to another.
Energy
100
This is the formula for calculating voltage in a circuit.
Voltage (volts) = Current (amps) multiplied by resistance (ohms)
100
This is the first property of light.
Light travels faster than anything else in the universe.
200
These are the units for measuring momentum OR impulse.
kilogram meters per second (kgm/s)
200
This method of heat transfer is the only way the sun can transfer its energy to Earth across the vacuum of space.
Radiation
200
A sound wave is this type of wave that oscillates parallel to its direction of motion.
Longitudinal wave.
200
Circuits that are low in resistance will have a high value for this.
Current
200
These are the ways to make light change direction.
Reflection and refraction
300
This is defined as change in momentum, and can be measured either in the units for momentum OR newton-seconds (Ns).
Impulse
300
Convection occurs because this property of gases and liquids causes warmer fluids to rise and colder fluids to sink.
Density
300
The speed of a wave's travel can be determined by multiplying these two things.
The frequency (in hertz) and the wavelength (in meters) of the wave.
300
In this type of circuit, all of the branches operate independently from one another.
A parallel circuit.

Looking through this device will show you a reduced and upright image of the object you're viewing.
A concave lens.
400
A force of 500 N is exerted on a basketball for 0.001 s. The change in momentum of the basketball is this.
500 N * 0.001s = 0.5 Ns or 0.5 kgm/s
400
This is characterized as the amount of disorder in a system.
Entropy
400
These two properties of a harmonic (self-sustaining and repeated) motion are inverse of each other.
Period (in seconds per cycle) and frequency (in cycles per second or hertz)
400
The Earth's magnetic poles are located in this orientation.
The Earth's north magnetic pole is located in the south geographic pole (Antarctic) and the south magnetic pole is located in the north geographic pole (the Arctic).
400
This will magnify a reflected image two ways in two directions.
A concave mirror.
500
A 200 kg cart is moving to the right at 4.7 m/s. A force of 90 N is applied over 3.2 s. This is the NEW momentum of the cart.
200 kg * 4.7 m/s = 940 kgm/s (original momentum) 90 N * 3.2 s = 288 Ns or kgm/s (change in momentum) 940 kgm/s + 288 kgm/s = 1228 kgm/s (new momentum)
500
The temperature 0 degrees Kelvin is also known as this.
Absolute zero.
500
This is the frequency of a sound wave with a wavelength of 0.1 m.
340 m/s (the speed of sound in air at standard temperature and pressure) divided by 0.1 meters = 3400 Hz.
500
A circuit with a 9-volt battery draws a current of 0.75 amps. This is the total resistance in the circuit.
9 V / 0.75 a = 12 ohms

A prism does this to light, separating it into its component colors.
