Physics Calculators (Page 16)
Velocity, mechanics, energy, electricity and physics tools.
Conical Pendulum Calculator
Compute the period and speed of a conical pendulum from length and angle.
1D Elastic Collision Calculator
Compute final velocities of a 1D elastic collision and verify momentum/energy.
Tsiolkovsky Rocket Equation Calculator
Enter initial mass, final mass and effective exhaust velocity to compute Δv=v_e·ln(m₀/m_f), mass ratio and propellant mass. m₀=100000, m_f=10000, v_e=3000 → Δv≈6908 m/s (escape ~11200 needs bigger ratio).
Simple Harmonic Motion Calculator
Enter mass m, spring constant k and amplitude A to get angular frequency ω=√(k/m), period T=2π√(m/k), frequency, max velocity Aω, max acceleration Aω² and total energy ½kA².
Inelastic Collision Calculator
Enter masses and velocities of two objects to compute the final velocity, momentum and kinetic energy lost in a perfectly inelastic collision.
Mass-Energy Equivalence Calculator
Enter mass and speed to compute energy via E = m·c² (rest energy) or relativistic kinetic energy E = (γ−1)mc².
Inclined Plane with Friction Calculator
Enter mass, incline angle, friction coefficient and gravity to compute the acceleration, force components and whether the block slides.
Brewster Angle Calculator
Compute Brewster's angle tanθ_B = n₂/n₁ for reflected polarization.
Double-Slit Interference Calculator
Compute fringe spacing Δy = λL/d for a double-slit experiment.
Radiation Pressure Calculator
Enter the light intensity I, area A, and reflectivity r to compute the electromagnetic radiation pressure P=(1+r)I/c and the radiation force F=P·A. Fully absorbing: P=I/c; fully reflecting: P=2I/c.
Photoelectric Effect Calculator
Enter light frequency (or wavelength) and work function to compute the maximum photoelectron kinetic energy, threshold and stopping voltage.
Single-Slit Diffraction Calculator
Enter wavelength, slit width and screen distance to compute the single-slit diffraction pattern: dark fringes at a·sinθ=mλ (m=1,2,3…), central maximum width 2Lλ/a. λ=550 nm, a=0.1 mm, L=1 m → central width 11 mm.
