Physics Flashcards
Speed (m/s)
distance (m) / time (s)
Acceleration (m/s^2)
change in velocity (m/s) / time (s)
Force (N)
mass (kg) x acceleration (m/s^2)
Weight (N)
mass (kg) x gravitational field strength (N/kg)
Efficiency
useful energy (J) / total energy (J)
Momentum
mass (kg) x velocity (m/s)
Wave speed (m/s)
frequency (Hz) x wavelength (m)
or
distance (m) / time (s)
Density (kg/m^3)
mass (kg) / volume (m^3)
Work done (J)
force (N) x distance (m)
Change in GPE (J/kg)
mass (kg) x gravitational field strength (N/kg) x change in vertical height (m)
Kinetic energy (J)
1/2 x mass (kg) x (speed (m/s))^2
Power (W)
work done (J) / time (s) or energy transferred (J) / time (s)
Energy transferred (J)
charge moved (C) x voltage (V)
Charge (C)
current (A) x time (s)
Voltage (V)
current (A) x resistance (Ω)
