Physics Flashcards
Magnitude of electric field
E = v/d
The relationship between electromagnetic radiation and frequency
Inversely proportional
Power (mW) x pulses duration (ms) =
Energy
Kinetic energy of a photoelectron =
hf -3.4 eV
Ohm’s law, R =
V/I. Maximum value of the current corresponds to minimum value of resistance
Focal length equation
1/f = 1/o + 1/i
Displacement
Change in position of an object. D = x(final) - x(initial)
Velocity
How fast an object’s position changes. V = delta x / delta t = d/ delta t
Acceleration
How fast an object’s velocity changes. A = delta v/ delta t
Free fall
Influence of acceleration due to gravity. G = 9.8 m/s^2
Projectile motion
Parabolic trajectory experiencing only the constant downward acceleration due to gravity
Delta x =
vt
