Everyday Physics - Calculators

Physics is the science of natural phenomena. Some of these, encountered at every turn, are easy to measure and calculate. This page provides tools for specific and general cases: Everyday Physics | Stone in Well | Lightning and Thunder | Echo | Light | Distance per Time | Distance at Speed | Work | Slide | Rotation | Pendulum | Radiation Dose | Acceleration | Gravity | Kilograms - Newtons | Kilograms - Liters | Add Forces | Intercept Theorem | Energy | Ohm's Law | Friction | Frequency | Conservation of Momentum | Pirouette Effect | Air Pressure - Altitude | Extrapolate Distance, Time | Measurement Error

Stopwatch

Very often time has to be measured. Here is a simple stopwatch which is accurate to tenths of a second. A more precise specification is not useful when measuring by hand.

Physics claims to explain the world as it is and how we perceive it. This applies to areas that constantly play a role in our daily lives and also to areas that we almost never have to deal with directly. For example, the first category includes the phenomenon of things falling down, which of course they don't actually do. Rather, when we are on earth, they move towards the center of the earth. This is called gravitation and we are constantly exposed to it.
The preferred means of physics to explain things is mathematics. Here, too, some areas are ubiquitous and others are very specific and hardly used by most people. The calculators on this site get by with basic arithmetic, some power calculus, and just a little bit of trigonometry.
The calculators presented here are from a generally accessible and recognized part of physics. Physics in itself is not a closed science. New insights have been made in the past that explain things better than the previous ones. This will probably also be the case in the future. Some things cannot yet be explained, others have contradictions. In general, however, physics provides a very good and mature picture of matter and energy, space and time and the interactions between them. Those areas of physics that are much more difficult to understand and explain, which mostly take place in the very smallest and the very largest, are not relevant for the everyday applications on these pages anyway.
