static friction | force that opposes motion of two systems that are in contact and are not moving relative to one another |
kinetic friction | friction between two systems that are in contact and moving relative to one another |
magnitude of static friction | f_s ≤ μ_s N |
magnitude of kinetic friction | f_k = μ_k N |
drag force | -proportional to square speed of object -F_D ∝ v^2 |
drag force formula | F_D = 1/2 C ρ A v^2 |
Stoke's Law | drag force of small objects moving in denser medium |
Stokes' Law formula | F_S = 6 π r η v |
elastic modulus | -calculates stretch of object -ΔL = 1/Y F/A L_0 |
tensile strength | max force that can be applied to certain material without causing it to fracture or permanently deform |
stress | -F/A -Y x strain |
strain | ΔL/L |
bulk modulus | -decrease in volume due to body subjected to forces on all side -ΔV = 1/B F/A V_0 |
Hooke's Law | proportional relationship between force on material and deformation it causes |
Hooke's Law formula | F = k ΔL |
