Physics Calculators (Page 29)
Velocity, mechanics, energy, electricity and physics tools.
Pulley System Calculator
Enter load force and number of supporting strands to compute the effort, mechanical advantage and rope pull of a pulley system.
Hydraulic Press Calculator
Enter input force and the input/output areas to compute the output force, mechanical advantage and distances via Pascal's principle.
Relative Velocity Calculator
Enter object speed v_A and observer speed v_B to compute relative velocity v'=v_A−v_B and closing speed |v_A−v_B|. Same direction subtracts, opposite adds. Two cars at 50 and −50 km/h → closing 100 km/h.
Work-Energy Theorem Calculator
Enter mass, initial and final velocity to compute the net work and kinetic-energy change W=½mv²−½mu². m=2 kg, u=3, v=5 → W=16 J; braking u=13.9, v=0 → W=−145 kJ.
Conservation of Momentum Calculator
Compute final velocity from momentum conservation in a collision.
Maximum Static Friction Calculator
Enter the static friction coefficient and normal force to compute the maximum static friction f_s,max = μ_s·N.
Vector Cross Product Calculator
Enter two 3-D vectors to compute the cross product a×b = (ay·bz−az·by, az·bx−ax·bz, ax·by−ay·bx), its magnitude |a×b|=|a||b|sinθ and the angle θ. a=(1,0,0), b=(0,1,0) → a×b=(0,0,1), |a×b|=1.
Vector Dot Product Calculator
Enter two 3-D vectors to compute the dot product a·b = ax·bx+ay·by+az·bz, their magnitudes |a|, |b| and the angle θ between them. a=(1,2,3), b=(4,5,6) → a·b=32, θ≈12.93°.
Uniform Acceleration Calculator
Solve the five uniform-acceleration (SUVAT) equations: v=u+at, s=(u+v)t/2, s=ut+½at², v²=u²+2as, s=vt−½at². Enter any 3 of u,v,a,s,t.
Vector Addition Calculator
Enter two 2D/3D vectors to compute their sum. a=(1,2,3), b=(4,5,6) → a+b=(5,7,9).
Vector Magnitude Calculator
Enter 3D vector components to compute magnitude and azimuth. a=(3,4,0) → |a|=5.
Vector Subtraction Calculator
Enter two 3D vectors to compute the vector difference. a=(5,7,9), b=(1,2,3) → a-b=(4,5,6).
