Physics I
True or False: Motion in the x direction is independent of motion in the y direction.
What is true?
Ohm's Law
What is V = IR.
Relate frequency and wavelength of a wave.
What is frequency = speed of light * wavelength?
The difference between a parallel circuit and a series circuit.
Parallel: current flows in multiple paths
Series: current flows in only one path.
Equation for Force.
What is Force = Mass x Acceleration/F=ma/Newton's Second Law?
Coyote is after the roadrunner again, but this time we are going to help him. We have a net 40 meters in the air and the roadrunner is running at 60 m/s. Assume we are on Earth and we are in a vacuum. How far should we put the big red "X" to let Coyote know when to drop the net?
d = 1/2*g*t^2
t = sqrt((2*d)/g)
t = 2.856 s
d = v*t = 60 m/s * 2.856 s
d = 171 m
What is 171 m?
Series circuit: (I will draw the circuit on the board)
V = 2V
2 resistors: R1 = 5 Ohms, R2 = 4 Ohms
I = ?
I = .222 A
Describe a standing wave.
The symbol for an LED.
What is a triangle with a line and two little arrows coming off of it?
The SI units for energy.
What are Joules?
Huott walked around the parade deck (about 200 meters per lap) three times, starting and ending at his beloved third battalion pad. The first lap took him 172 seconds, the second lap took 190 seconds and his third lap took 228 seconds. What is Huott's average velocity of his entire trip?
average v = (d_final - d_initial)/time
He started and ended at the same place, meaning he made it a grand total of 0 meters in any direction, therefore his average velocity is 0 m/s.

4 Capacitors: C1 = 3 nF, C2 = 5 nF, C3 = 4 nF, C4 = 6 nF
Ceq = 4.4 nF
If theta = A*cos(w*t), what is theta double dot?
theta double dot = -w^2 * A * cos(w*t)
Two things an OpAmp can do.
Compare voltages, amplify voltages, multiply, divide, integrate, differentiate, (if you have something else, it can probably do it, but will look it up just to make sure)
Ideal Gas Law, variables defined.
What is PV = nRT, where P is pressure, V is volume, n is number of moles, R is the gas constant and T is the temperature.
