Velocity & Acceleration Calculator

Free projectile motion calculator for horizontal, oblique (angular), and vertical projectiles — range, max height, time of flight, and impact speed with an animated trajectory.

Free impulse calculator — J = F·Δt = m·Δv, with peak force as well as average, deceleration in g, and an animated impact beside a force–time curve whose shaded area is the impulse.

Free torque calculator — τ = F·r·sinθ in N·m, lb·ft, lb·in and kg·cm, with the effective lever arm drawn as a perpendicular you can watch collapse as the angle closes, plus angular acceleration from τ = Iα.

Free momentum calculator — p = m·v in kg·m/s, with the kinetic energy alongside so you can see why momentum and energy are different ideas, a stopping force from any stopping time, and a second object to compare against.

Free SHM calculator for a pendulum or a mass on a spring — period, frequency, angular frequency, maximum speed and acceleration, with a live animation beside a synchronised graph of position, velocity and acceleration.

Solve a one-dimensional collision between two bodies and watch it happen: elastic bounces, perfectly inelastic sticking, and every coefficient of restitution in between, with momentum and kinetic energy side by side.
