Formula Sheet for PHY 101 Final Exam Ch 2-7,9-10,19, 26-29 ! [In some relations, the “~” symbol is being use to represent a direct proportion]

Ch 3: Linear Motion a = Δ v/t vf = vi + at

(average acceleration) (final velocity: how fast?)

vavg = Δd/t (average velocity) Δd = vavgt (displacement: how far?)

Δ d = vit + 1/2 at2 (full displacement formula) d = 1/2 gt2 (falling from rest)

Ch 2, 4 and Ch 5: Newton’s Laws Fnet = 0 or no acceleration (condition for dynamic OR static equilibrium) Fnet = ma (net force); Ff = µN (friction and normal force relation) [g = -10 m/s2]

W = mg

(weight and acceleration of gravity)

a = (R+W)/m (falling with air resistance; R opposes W) p = mv (momentum); Ft = m(vf-vi) (impulse = change of momentum) m 1v1 + m 2v2 = m 1v1’ + m 2v2’ m1v1 + m2v2 = (m1+ m2)v’

(completely elastic collision) (completely inelastic collision)

Ch 7: Work and Energy (and Simple Machines!) W = Fd

(work)

PE = mgh KE = 1/2mv2

P = W/t = Fd/t

(power)

(potential and kinetic energy)

ΔKE + ΔPE = 0, or KE gained = PE lost, results in: mgh = 1/2mvf2

%eff = Work output / Work input or AMA / IMA (efficiency) Wout = Frdr

Win = Fede (work due to effort and resistance forces and distances) IMA = de/dr (Ideal Mechanical Advantage) AMA = Fr/Fe (Actual Mechanical Advantage) Ch 9-10: Gravity and Projectile Motion:

F = mg

F = G m1m2/d2

(Universal Law of Gravity)

horizontal: Fnet = 0, ax = 0, vx = const, dx = vxt, ttotal = tup + tdown vertical: Fnet = mg, ay = g, vf = vi + gt, dy = 1/2gt2, (tdown )2 = 2dy/g ]

Ch 19 (and Light Basics slides): v = fλ = λ/Τ

T = 1/f

f = 1/T (wave relationships)

fpeak ~ T or λ peak ~ 1/T (blackbody curve) Ch 26 & 27 & 30 (Color and Light Properties) c = fλ

E = hf

c = 3.00 x 108 m/s (electromagnetic spectrum)

R+G+B=W

(primary color addition)

R + G = Y; R + B = M; B + G = C (color addition) Ch 28 & 29 (Optical Behavior) θi = θ r

(law of reflection)

n = c/v

(index of refraction)

n2/n1 ~ θ1/θ2 (law of refraction: if n2>n1, then θ2...
