Formula Sheet Flashcards
1
Q
F = μN
A
F = friction force μ = coefficient of friction N = normal reaction
2
Q
μ = tan θ
A
μ = coefficient of friction θ = friction angle
3
Q
KE = ½ mv²
A
KE = kinetic energy m = mass v = velocity
4
Q
PE = mgh
A
PE = potential energy m = mass g = gravitational acceleration h = height
5
Q
W = Fs = ∆PE + ∆KE
A
W = work F = force s = distance ∆PE = change in potential energy ∆KE = change in kinetic energy
6
Q
P = W/t
A
P = power W = work t = time
7
Q
P = Fs/t
A
P = power F = force s = distance t = time
