Average Velocity
x(t2) - x(t1) / t2 - t1
Same as Δx / Δt
The general form of a particle at a given time with constant acceleration
x(t) or y(t) = (1/2)at^2 + bt + c
Gravity “Constant”
9.8 m/s^2
Velocity with Constant Acceleration
V = V not + a(t)
Potential Energy
PE=mgh
Kinetic Energy
(1/2)mv^2
Final Velocity of Two Components
Vx^2+Vy^2=Vf^2
Pythagorean Theorem
Centripetal Acceleration
Ac = V^2 / r
r = radius, Ac = (given) x (g=9.8)
Displacement Equation
Δx = V initial * t + (1/2)at^2
Velocity Equation
V final = V initial * (a)(t)
Velocity Squared
(Vf)^2 = (V not)^2 + 2aΔx
Tangential Speed
V = rω
Angular Velocity
ω = 2πf
Where f consitutes frequency
Horizontal Distance
Dh = Vx * T
Where Vx=cos(θ)
Vertical Distance
y = Vyi * T - (1/2)g(t)^2
Where Vyi = V(not)sin(θ)
i = initial
Period
T = 1/f
