the goal of this website is to help students find the equations they need for their classes, and to help them understand how to use them.

this website is not meant to be a replacement for a textbook or a teacher, but rather a supplement to help students find the equations they need and to understand how to use them.

This website contains equations for these classes | Algabra 1, Algabra 2, Geometry, Pre-calculus, Calculus, Physics, Chemistry, Psychology, Engineering, Accounting, stats, and Financial Literacy |

special characters that physics uses

∆

delta is a symbol used in math to represent change or difference. It is often used to indicate a change in a quantity, such as velocity (∆v) or position (∆s).

tau is a symbol used in physics to represent torque or time constant.

lower case omega is a symbol used in physics to represent angular frequency or angular velocity.

lowercase eta primarily represents efficiency (the ratio of useful output to total input) and dynamic viscosity (a fluid's resistance to flow)


momenteom equation	P=m*v	the formula for momentum, where (p) is momentum, (m) is mass, and (v) is velocity
Gravitational force	fg=m*g	represents the force of gravity (Fg) acting on an object with mass (m), where (g) is the acceleration due to gravity (approximately 9.8 m/s² on Earth)
Newton's Second Law	f=m(dv/dt)	newtons second law of motion states that the net force (f) acting on an object is equal to its mass(m) times its acceleration (dv/dt).
velocity	v=∆s/∆t	this equation represents average velocity (v) delta (∆) or change in speed (s) divided by change in time (t).
acceleration	a=∆v/∆t	this equation represents average acceleration (a) delta (∆) or change in velocity (v) divided by change in time (t)
rotational dynamics	τ=I(dω/dt)	this equation represents the torque (τ) acting on a rotating object, where (I) is the moment of inertia and (dω/dt) is the angular acceleration.
newtonian fluids	Fₓ/A=η((dx*dz)/dt)	this equation represents the relationship between shear stress (Fₓ/A) and the rate of strain (dx*dz/dt) in a Newtonian fluid.
thermal conduction rectangular	Q̇=k*A(∆T/∆x)	this equation represents the rate that heat trasfers in a rectangular object with (Q̇) representing the rate of transfer, (k) representing the objects thermal conductivity, (A) representing the objects cross senction, and (∆T) is the tempeter difference and (∆x) being the thickness.
