Physics Flashcards
What is the coefficient of friction equation
What is the force equation?
mass x gravitational acceleration
What is Doppler shift for laser sensors?
When the light reflects off of an object moving towards the sensor, it will reflet back with a higher frequency. When object is moving away from the sensor, the light will reflect back at a lower frequency.
What is Potential energy equation?
PEinit =mgh
What is Kinetic energy equation?
KE = 1/2 mv^2
Cardiac output is proportional to what?
Heart rate
How do you add capacitors in series?
How do you add capacitors in parallel?
What is the formula for acceleration
a = F/m
or
a=change in velocity over change in time
What is the formula for displacement?
What is inertia proportional to?
The mass of the object and therefore its static friction force.
I = angular momentum (L) / angular velocity (w)
What is the formula for distance on a speed vs time plot?
d = 1/2bh
What is the formula for distance?
d = speed x time
or
with no speed given look below
How is work related to kinetic energy of a moving object?
W = KE fin - KE int
KE =1/2mv^2
What is the equation for power?
P = Work / time
What is the specific heat equaion?
Q = m x c x delta T
What are the equations for Power?
P=V^2/R
P=IV
P=I^2R
Is the angle of incidence equal to the angle of refraction or reflection?
Reflection
Power equation?
power = work / time
What is the equation relating distance, acceleration, and velocity?
Vf^2 = Vi^2 +2ad
What is the capacitance equation?
C = q/V
Where C is in farads and q is C
How does depolarization occur?
the gated sodium ion channels on the neuron’s membrane suddenly open and allow sodium ions (Na+) present outside the membrane to rush into the cell.
How is the spring constant related to PE?
PE = ½kx^2
where k is the spring constant in N/m and x is the displacement
What are the four major acceleration equations?
What is a power equation relating energy and time?
P = E / delta t
How do you find heart rate?
HR = 1/T
T = the time when PPG is zero before and after a heart beat
What is a state function?
What is a process function?
How is Work related to pressure and volume?
W = P x delta V
What is coduction?
The transfer of heat through direct contact
What is convection?
The transfer of heat through the flow of fluids
What is the relationship between resistance, resistivity, length and cross sectional area
R = p x (L/A)
What is the continuity equation?
A1V1=A2V2
where A is the cross sectional area. For example, a pipe or blood vessel would be pi (d/2)^2
What is an isolated system?
Neither heat nor matter can be exchanged with the surroundings
What is a closed system?
Only heat, not matter, can be exchanged with the surroundings
Linear motion equaitons
V = Vo +at
x = Vot + at^2/2
V^2 = Vo^2 + 2ax
x = vt
Force of a parallel component of gravity on an inclined plane
F = mg sin(x)
Force of the perpendicular component of gravity on an incline
F = mg cos(x)
Force in circular motion
F = mv^2/r
What is conduction?
The transfer of energy from molecule to molecule (molecular collisions)
What is convection?
The transfer of heat by the motion of a fluid over a material
What is radiation?
Transfer of energy through EM waves
