Okay i have this topic so that if i forget a formula or i don't know one(or if anyone does,i think everyone forgets one) i could just come here and look it up.Also add formulas that i missed (im in middle school i have not learned them all!)
Force:Mass*Acceleration
Mass:Force/Acceleration
Acceleration:Force/Mass
Pressure:Force/Area
Work:Force*Distance
Power:Work/time or Energy/time
Mechanical Energy: Kinetic energy+ Potential energy
Kinetic energy:1/2mass*velocity*velocity (or something like that)
Potential energy:Mass*acceleration of gravity*Height
MATH FORMULAS=
Volume for any 3d figure:area of base* height
Volume for a Sphere:4/3Pi*radius*r*r*r
Area for Triangles:Base*height/2
Area for a circle:Pi*Radius squared
Circumference of a circle:Pi*Diameter squared
Area for a Trapezoid:(Base1+base2)*height/2

thats all i know thanks for helping me!

I believe there is a website for this purpose called Wikipedia. Also WolframAlpha

for force and mass/acceleration, just remember FEMA. Force Equals Mass*Acceleration
