It's also good to know the superposition principle, as well as how frequency is quantized for a string with fixed endpoints.
The only necessary equation is v = λ f (If you have the math background, the wave equation could come in handy, but it's probably definitely overkill).
Pressure relative to the surface of a fluid: ΔP = ρ g hīe able to analytically solve the Navier-Stokes equations justkidding Pendulum period and frequency: f = 1 / (2π) √(g/L), T = 2π √(L/g) Small angle approximation for a pendulum: θ'' = -(g/L) sin(θ) ≈ -(g/L) θ Period and frequency: f = ω / (2π), T = 1 / f The solution to that equation: x = A cos(ω t + φ), where A is the amplitude, φ is the phase, and ω = √(k/m). Mathwise, I believe that physics 101 is algebra only, which shouldn't be too bad. When doing a problem, look at the information you are given, and find the equation that contains those variables and the variable you are looking for. The differential equation for a simple harmonic oscillator: x'' = -(k/m) x What you need to do is create an equation sheet for each chapter. In this article we consider a graphene sheet that is folded in various. Useful equations Physical constants Waves 2.998×108 m/s 6.626 × 1034 J s 4.135 × 1015 eV s 1. The first is the matrix Weyl equation describing cyclotron motion of a charged. They'll probably give you a table, but you might want to have the formulas common shapes (rod, cylinder, sphere, etc) written down.

It's good to know how to calculate moment of inertia with a double/triple integral, but they won't ask you to do that. In 1941, Rosalyn Sussman Yalow arrived at Illinois to embark on her Ph.D. Rotational kinetic energy: Er = 1/2 I ω 2 Moment of inertia for a single particle: I = m r 2 When you represent an angular quantity as a vector, it's along the axis of rotation, in a direction given by the right hand rule.ĭefinitions of angular velocity and acceleration: ω = dθ/dt, α = dθ/dtĬonverting between linear and angular: s = r θ, v = r ω, a = r αĪngular kinematics (same as linear): θ = θ0 + ω0 t + 1/2 α t 2 In addition, you should have a good grasp of conservation of angular momentum.Īlso, right hand rule! Seriously, get good at it now, cause when you're in 1120, or E&M, or plasma physics ( especially plasma physics), you need to have that shit down cold. For example, the equations α = dω/dt and τ = I α are analogous to a = dv/dt and F = m a. The most important thing to remember here is that all quantities are rotational analogues of position, velocity, acceleration, force, mass, and momentum.
