Physics Calculators (Page 10)
Velocity, mechanics, energy, electricity and physics tools.
Thin Lens Calculator
Enter focal length f and object distance do; the thin-lens equation 1/f=1/do+1/di gives image distance di instantly. f=10 cm, do=30 cm → di=15 cm (real image).
Magnification Calculator
Enter object and image distances to compute the linear magnification m = −d_i/d_o of a lens or mirror.
Spring Constant Calculator
Enter force and extension to compute the spring constant k=F/x. F=20 N, x=0.1 m → k=200 N/m. k measures stiffness: larger k = stiffer spring.
Impulse Calculator
Enter force and time to compute impulse J = F·Δt (equal to change in momentum).
Thermal Conduction Calculator
Enter conductivity k, area A, temp difference ΔT, time t and thickness d to compute conducted heat Q=k·A·ΔT·t/d. k=0.8, A=2, ΔT=20, t=3600, d=0.1 → 1.15 MJ.
Refractive Index Calculator
Find refractive index from light speed in a medium, or from Snell's law at an interface. n=c/v. Water n≈1.333; glass≈1.5; diamond≈2.42.
Young's Modulus Calculator
Enter force, original length, cross-sectional area and extension to compute Young's modulus E=FL/(A·ΔL). F=100 N, L=1 m, A=1e-4 m², ΔL=1e-3 m → E=1e9 Pa (1 GPa).
Magnetic Force Calculator
Enter charge, velocity and magnetic field to compute the magnetic force F = q·v·B·sinθ on a moving charge.
Kinetic Friction Calculator
Compute kinetic friction F_k = μ_k·N.
Buoyancy Force Calculator
Compute buoyant force = ρ·V·g for a submerged volume.
Angular Momentum Calculator
Compute angular momentum L = I·ω.
Lens Power Calculator
Compute optical power P = 1/f (in diopters) of a lens.
