Physics Calculators
Every physics calculator on the site, in one place - motion, energy, force, and waves, grouped by what you're solving for.
Each tool shows its formula and a fully worked example directly on the page. Every calculation runs in your browser and nothing you enter is saved. Jump to a section, or scroll through all 14.
Motion
Speed, acceleration, falling, and flight.
- Velocity Calculator - velocity, distance, or time from the other two.
- Acceleration Calculator - acceleration from initial velocity, final velocity, and time.
- Free Fall Calculator - fall time and final velocity from a drop height.
- Projectile Motion Calculator - range, max height, and time of flight from launch speed and angle.
Energy & work
Kinetic energy, potential energy, work, and power.
- Kinetic Energy Calculator - the energy of a moving object from mass and velocity.
- Gravitational Potential Energy Calculator - stored energy from mass, height, and gravity.
- Work Calculator - work, force, or distance from the other two.
- Power Calculator - power, work, or time from the other two.
Force & momentum

Frequently asked questions
Are these physics calculators free to use?
Yes - all 15 tools on this page are free, with no account or sign-up required.
Do these account for real-world factors like air resistance and friction?
Most use the standard idealized equations taught in introductory physics, which generally ignore air resistance and friction for simplicity. Each calculator's page notes clearly where this idealization matters most, like Free Fall and Projectile Motion.
Are these useful for a physics class, or just for reference?
Both - each tool shows the underlying formula and a worked example, making them useful for checking homework, building intuition, or just getting a quick answer for a real-world question.
Is any of the information I enter saved?
No. Every calculation runs directly in your browser - nothing you type is sent to a server or stored anywhere.
