# Physics Equations

∆x = x-xi Displacement
s = d/t Average Speed
v = ∆x/∆t (or) x = x-xi/t-ti Average velocity
v = v+vi/2 Average Velocity
a = ∆v/∆t (or) a = v-vi/t-ti Average acceleration
f_net = ma Net force (sum of all forces acting on that object)
w = mg weight
f_g = mg Force of gravity
f~. = .~f Newtons third law
v = vi +at FOR KINEMATIC PROBLEMS
x = xi+1⁄2(v+vi)t FOR KINEMATIC PROBLEMS
x = xi+vi(t)+1⁄2at^2 FOR KINEMATIC PROBLEMS
v^2 = vi^2+2a(x-xi) FOR KINEMATIC PROBLEMS
v = vi+gt FOR KINEMATIC FREES FALL PROBLEMS
y = yi+1⁄2(v=vi)t FOR KINEMATIC FREES FALL PROBLEMS
y = yi+vi(t)+1⁄2gt^2 FOR KINEMATIC FREES FALL PROBLEMS
v^2 = 2g(y-yi) FOR KINEMATIC FREES FALL PROBLEMS
