Formula Cheat Sheet
MATH
Area of Circle
A = πr²
Where r is the radius of the circle.
MATH
Area of Triangle
A = ½ × b × h
b = base, h = height.
MATH
Pythagoras Theorem
a² + b² = c²
For right-angled triangles.
PHYSICS
Newton's Second Law
F = m × a
F = force, m = mass, a = acceleration.
PHYSICS
Mass-Energy Equivalent
E = mc²
Conservation of energy and mass.
PHYSICS
Velocity
v = d / t
d = distance, t = time.
CHEMISTRY
Ideal Gas Law
PV = nRT
P=pressure, V=volume, n=moles, R=constant, T=temp.
CHEMISTRY
Density
ρ = m / V
m = mass, V = volume.
CHEMISTRY
Molarity
M = n / V
n = moles of solute, V = liters of solution.
