Formula to get pressure at bottom of tank (treated as closed tank)
ρgh
Value of Atmospheric Pressure
101.3 kPa
Open tank Pressure formula
P atm + ρgh
Acceleration of gravity
9.8 m/s²
Free fall: height and time formula
h = (gt²) / 2 t = √(2h/ g)
2 dimensional kinematic equations for y axis
photo
Angular velocity units
radians/sec
Torque formula with moment of inertia
T = Iα
where I is moment of inertia and α is angular acceleration
Angular momentum formula
L = mvr = Iω
where I is moment of inertia, ω is angular velocity
Laws of thermodynamics
Zeroth = equals = if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. First = internal energy and conservation Second = entropy is always increasing Third = absolute zero is entropy zero
1 calorie is equal to how many Joules?
4.184J

Index of refraction formula
n = c/v
Where c is speed of light in vacuum and v is speed in medium
Lens equation
-diverging VS converging lens
1/f = 1/do + 1/di
Where f is (-) when diverging and (+) when converging
Magnification equation
hi/ho = -di/do
Formula capacitance
Q = CV
Where Q is charge, C is capacitance and V is voltage
De Broglie’s equation
λ = h / (mv) Where λ Is wavelength h is Planck's constant m is mass v is velocity
