PHYS 200 Unit 5: Further Applications of Newton's Laws: Friction, Drag, and Elasticity

Questão	Responda
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
