Free Astronomy & Physics Science Hub No Email Needed
Physics and astronomy calculators for real-time moon phases and lunar illumination, 2D projectile motion trajectories, kinetic and potential mechanical energy, and Magnus dew point heat index.
Moon Phase & Lunar Calendar Calculator
Calculate real-time moon phase (New Moon, First Quarter, Full Moon, Waning Crescent), lunar illumination percentage, and days in the 29.53-day synodic cycle.
Free Fall & Projectile Motion Calculator
Calculate kinematic free fall velocity, drop duration, projectile launch trajectory, maximum height apex, and total horizontal range under gravitational acceleration.
Kinetic & Potential Energy Calculator
Calculate kinetic energy (Ek = 1/2 mv²), gravitational potential energy (Ep = mgh), and total mechanical energy conservation in Joules, Kilojoules, and Calories.
Dew Point & Heat Index Calculator
Calculate exact dew point temperature using the Magnus-Tetens formula, relative humidity %, and NOAA heat index apparent temperature comfort ratings.
About the Astronomy & Physics Science Hub
Classical Newtonian physics and astronomical ephemerides govern our physical world. The Astronomy, Physics & Environmental Science Hub provides interactive kinematic simulators and atmospheric thermodynamic tools.
Track the 29.53-day synodic lunar cycle for astrophotography planning, compute 2D parabolic projectile flight paths across Earth, Mars, and the Moon, verify kinetic versus potential energy conservation in Joules, and evaluate atmospheric humidity with the Magnus dew point equation.
