Heres the formula sheet everybodys been dying for
V = Vi + A*T V^2 = Vi^2 + 2*A*D (D is distance) X = Xi + Vi*T + 1/2*A*T^2 (formula of the year)
Vx = V*cos(theta) Vy = V*sin(theta) Calculating magnitude: V = sqrt(Vx^2 + Vy^2) - when given components and finding magnitude
of final vector Calculating angle: tan(theta) = Vx/Vy = when given components and finding angle of final
vector
F=MA (obviously) Fg = MG (Force of gravity = Mass * Acceleartion due to gravity), Accel due to Grav = 9.8
m/s^2
Centripetal Accel = V^2/R = 4(pi)^2*R/T^2 Gravity = G*M1*M2/R^2, G = 6.67e-11
Work = F*D*cos(theta) [D is distance, theta is angle of which the force was applied] KE = 1/2*M*V^2 PE = M*G*H (M is mass, H is height above ground) Work = change in KE = 1/2*M*Vf^2 - 1/2*M*Vi^2
P = M*V (P is momentum) F*t = change in momentum, F*t is called the impulse Nonelastic Collision - M*Vi = M*Vf Elastic - 1/2*M*Vi^2 = 1/2*M*Vf^2
w = theta / t (w is angular veloctiy) a = w/t v = r*w a[tangential] = ra

springs: F = kx PE = 1/2*k*x^2 Frequency = 1/Period T = 2(pi)*sqrt(m/k) --- T is period, M is mass, K of spring Pendulum: T = 2(pi)*sqrt(L/G) --- T is period, L is length of string, G is gravity
acceleration Vel = (wavelength) * (frequency) --- velocty of a wave
F = k(Q1*Q2)/d^2 - Q1 and Q2 are charges on particles, k = 9.0e9 Can be rewritten as F = 1/(4*pi*E) * Q1Q2/d^2, E is permeability of free space = 8.85e-12
E = k*Q/r^2 - E is strenght of electric field, k=9.0e9 |
