10 Free Physics Calculators Every Student Needs — Velocity, Force, Energy & More
Physics homework just got easier. We launched 10 new physics calculators — all free, private, and browser-based. No signup, no app, no data collection. Every calculation shows step-by-step working so you can learn the process, not just get the answer.
1. Velocity Calculator
Calculate average velocity, final velocity, initial velocity, angular velocity, and even escape velocity. Five modes in one tool.
Enter displacement and time, or initial velocity + acceleration + time, and get instant results with unit conversions (m/s to km/h) and complete step-by-step working.

2. Force Calculator
Six calculation modes: Newton's Second Law (F=ma), gravitational force, weight, centripetal force, spring force (Hooke's Law), and net force vector addition.
Perfect for solving homework problems — enter your values, get the answer with every step shown.

3. Acceleration Calculator
Calculate linear acceleration, acceleration from force, centripetal acceleration, gravitational acceleration on different planets (Earth, Moon, Mars, Jupiter), and angular acceleration.
Includes g-force equivalents so you can understand what the numbers actually feel like.

4. Kinetic Energy Calculator
Five modes: calculate KE from mass and velocity, find mass from energy, find velocity from energy, relativistic kinetic energy, and the work-energy theorem.
Results shown in Joules, kJ, and ft·lbf with full step-by-step solutions.

5. Potential Energy Calculator
Calculate gravitational PE (mgh) and elastic PE (½kx²). Switch between planets to see how gravity affects stored energy. Find mass, height, or spring constant — the calculator solves for any variable.

6. Projectile Motion Calculator
This one has a visual trajectory graph. Enter initial velocity, launch angle, and height — get range, max height, flight time, and impact velocity. The canvas draws the full parabolic path with labeled axes.
Perfect for understanding how angle affects range and height.

7. Momentum Calculator
Calculate linear momentum, solve for mass or velocity, and solve collision problems — both elastic and inelastic. The collision solver shows final velocities, verifies conservation of momentum, and calculates kinetic energy lost.
Also includes an impulse calculator (J = Ft).

8. Resistance Calculator
Five modes: Ohm's Law (R=V/I), series resistance, parallel resistance, resistor color band decoder (visual 4-band reader), and power dissipation.
The color code decoder is especially useful for lab work — select the band colors and instantly get the resistance value.

9. Half-Life Calculator
Dual-purpose tool for physics AND pharmacology. Calculate remaining quantity after radioactive decay, find the half-life period, elapsed time, or decay constant.
The drug half-life mode includes presets for caffeine, ibuprofen, aspirin, and acetaminophen — showing how much remains in your body over time.
