Physics Calculators
Evidence-based physics calculators. Calculate projectile motion, kinematics, and forces — free, accurate, and with no account required.
Projectile Motion Calculator
Calculate the trajectory, max height, range, and flight time of a projectile.
Volts to Joules Calculator
Convert voltage to electrical energy in Joules using charge (V × Q) or current and time (V × I × t).
Understanding Physical Laws & Equations
Physics is the study of matter, energy, and their interactions. Computing kinematic trajectories, tracking thermodynamics, and converting electrical parameters require using fundamental formulas derived from Newton, Coulomb, and other classic equations.
Our physics calculators are engineered to compute these variables instantly, translating inputs (like initial velocity, launch angle, capacitance, and charge) into precise values for energy, velocity vectors, and peak heights.
Simulating Mechanical & Electrical Systems
Solving equations by hand for multi-stage systems (such as projecting a ball's position at every millisecond or finding electrical potentials under varying charges) is time-consuming.
These interactive calculators let you input variables under standard environments (e.g. Earth's standard gravity of 9.80665 m/s²), showing you breakdown curves and exact vectors to simplify lab experiments, engineering assignments, and home projects.
Frequently Asked Questions
How do you convert Volts to Joules?
Volts measure electrical potential, while Joules measure energy. To convert between them, you must know the charge in Coulombs (J = V × Q) or the capacitance and voltage in a capacitor circuit (J = 0.5 × C × V²).
Is air resistance included in projectile calculations?
Our basic projectile calculators assume an ideal vacuum environment without drag to align with classic physics curricula, but provide complete velocity vector breakdowns for every stage of flight.
