Physics Equations Flashcards
What is the density formula?
Density (kg/m3) = mass (kg) / volume (m3)
What is the equation for acceleration?
Acceleration (m/s2) = change in velocity (m/s) / time (s)
What is the equation for kinetic energy?
Kinetic energy (j) = 0.5 X mass (kg) X Speed^2 (m/s)
What is the equation for force?
Force (N) = mass (kg) X acceleration (m/s)
What is the equation for work done?
Work done (j) = force (N) X Distance (m)
What is the equation for power, including work done?
Power (W) = work done (J) / time (s)
What is the equation for momentum?
Momentum (kgm/s) = mass (kg) X Velocity (m/s)
What is the equation for pressure, including force?
Pressure (Pa) = Force (N) / Area (m2)
What is the equation for weight?
Weight (N) = gravity force (N) = mass (kg) X GFS (N/KG)
The GFS on Earth is always 10 N/KG
What is the equation for gravitational potential energy?
GPE (J) = mass (kg) X height (m) X GFS (N/KG)
What is the equation for a moment?
Moment (Nm) = force (N) X distance (m)
What is the equation for charge flow?
charge flow (C) = current (A) × time (s)
What is the equation for potential difference?
potential difference (V) = current (A) × resistance (Ω)
What is the equation for energy transferred including charge?
energy transferred (J) = charge (C) × potential difference (V)
What is the equation for power, including potential difference
power (W) = potential difference (V) × current (A)
