Physics equations Flashcards
What is the equation for DENSITY ?
P = m / v Density = mass / volume
What is the equation for ENERGY ?
using time
E = p x t Energy = power x time
What is the equation for ENERGY ?
Using charge
E = Q x V Energy = charge x voltage
What is the equation for CHARGE ?
using time
Q = I x T charge = current x time
What is the equation for VOLTAGE ?
V = I x R Voltage = current x resistance
What is the equation for WORK DONE ?
W = V x Q
Work done = voltage x charge
What is the equation for POWER ?
Using voltage
P = I x V Power = current x voltage
What is the equations for POWER ?
Current
P = I (2) x R Power = current squared x resistance.
What is the equation for (gravitational) potential?
Egp = MASS x HEIGHT x GRAVITY
what is the equation for (ELASTIC) POTENTIAL?
Ek = 0.5 x MASS x VELOCITY squared
