F=Δp/Δt - Force (N) = Change in Momentum (Ns)/Change in Time (s)
F=Δp/Δt - Avg. Force from collision
F = Force (N)
Δp= Change in momentum (Ns)
Δt=Change in Time (s)
R = mgcos(θ) - Normal Force
R = Normal Force (N)
m = Mass (kg)
g = Acceleration due to gravity (9.81 m/s^2)
θ = Slope Angle (°)
F_f ≤ µ_s*R - Force of Static Friction (Not Moving)
F_f = Force of Friction (N)
µ_s = Coefficient of Static Friction (0-1)
R = Normal Force (N)
F_f = µ_d*R - Force of Dynamic Friction (Moving)
F_f = Force of Friction (N)
µ_d = Coefficient of Dynamic Friction (0-1)
R = Normal Force (N)
Impulse=Δp=FΔt - Impulse = Change in momentum
F = Force (N)
Δp= Change in momentum (Ns)
Δt=Change in Time (s)
c=fλ - Speed of a Wave
c = wavespeed (m/s) [For E&M wave it's the speed of light]
