Everyday physics and experiments Calculators

Buoyancy Experiment Calculator Use our buoyancy experiment calculator to estimate the density of dish soap (or an unknown liquid). You'll need to use salt water, a ball, a vessel, a measuring tape, and a weight. Flat vs. Round Earth Calculator Omni's not-flat Earth calculator helps you perform three experiments that prove the world is round. Hair Diffraction Calculator Measure the width of your hair using a laser and physics. This hair diffraction calculator will help you set up the experiment, understand the physics behind (hair) diffraction patterns, and, of course, calculate the width of your hair. Immersed Weight Calculator The immersed weight calculator helps you understand why objects float or sink in different liquids and guides you through DIY experiments to see firsthand how immersing something in various liquids affects its weight in different ways. Mass Moment of Inertia Calculator The cylinder mass moment of inertia calculator is a tool that can help you find out which cylinder/cylindrical shell/ cylindrical tube will run faster in an eventually do it yourself race experiment. Projectile Motion Experiment Calculator Blast off with this super fun projectile motion experiment calculator! Create a simple launcher and learn the basics of projectile motion. Smartphone Projector Calculator In this smartphone projector calculator, you will learn how to make your very own DIY smartphone projector with a shoebox and a magnifying glass. Experiment with it and learn how to find the focal length of your magnifying glass lens. Sun Angle Calculator Our sun angle calculator helps you estimate the Sun's position in the sky regarding its elevation and azimuth angles. Sunrise Sunset Calculator Estimate the sunrise and sunset times in your local timezone based on your location using the sunrise sunset calculator.
