Force Calculator
Calculate force using Newton's second law: F = ma. Supports mass in kg and acceleration in m/s².
Kinetic Energy
Calculate kinetic energy (KE = ½mv²) for any moving object with mass and velocity.
Potential Energy
Calculate gravitational potential energy (PE = mgh) with mass, gravity, and height.
Gravity Calculator
Calculate gravitational force between two masses using Newton's law of gravitation.
Escape Velocity
Find the escape velocity needed to break free from a planet's gravitational pull.
Orbital Velocity
Calculate the velocity needed for a stable orbit around any celestial body.
Ohm's Law
Calculate voltage, current, or resistance using V = IR. Solve for any electrical variable.
Power Calculator
Calculate electrical or mechanical power (P = W/t or P = IV) for any scenario.
Mass-Energy (E=mc²)
Calculate energy from mass using Einstein's famous E=mc² equation.
Speed Calculator
Calculate speed, distance, or time using the formula: speed = distance ÷ time.
Density Calculator
Calculate density, mass, or volume using ρ = m/V for any material.

Convert between Celsius, Fahrenheit, Kelvin, and Rankine instantly.
Frequently Asked Questions
What science calculators are available?
12 calculators covering force, kinetic energy, potential energy, gravity, escape velocity, orbital velocity, Ohm's law, power, mass-energy (E=mc²), speed, density, and temperature conversion.
Are these good for physics homework?
Yes. Each calculator shows the formula used, accepts standard SI units, and provides step-by-step results — ideal for checking homework and understanding concepts.
How do I calculate escape velocity?
Use our Escape Velocity Calculator. The formula is v = √(2GM/r), where G is the gravitational constant, M is the planet's mass, and r is its radius.
