# Mechanics lessons

Here you will learn the laws of motion of bodies (e.g. particles, cars, planets) under the influence of physical forces. Master the power to predict the future location and state of these bodies - no matter if the body is particle-like or wave-like.
Lesson
Level 3 (with higher mathematics)

## Lorentz Transformation as Rotation or Lorentz Boost

Here you will learn about the properties of the Lorentz transformation as well as rotations in space and Lorentz boosts.

Lesson
Level 2 (without higher mathematics)

## Uniform Circular Motion and its Important Quantities

Uniform circular motion from physics simply explained - here you will learn about centripetal acceleration and centripetal force and how they arise.

Lesson
Level 2 (without higher mathematics)

## Physical Quantities and Their Units

List of important physical quantities, their symbols, (derived) units and examples with images.

Lesson
Level 2 (without higher mathematics)

## The 12 Important Physical Constants

Learn about important physical constants and what their formula symbols and SI units are.

Lesson
Level 1 (suitable for all)

## Mechanical Momentum in Physics

Here it is explained quite simply what the mechanical momentum is, how you can calculate and illustrate it.

Lesson
Level 2 (without higher mathematics)

## What is the (Angular) Wavenumber?

Here you will learn how wavenumber is defined, how it can be calculated and illustrated, and how it is related to angular wavenumber.

Lesson
Level 3 (with higher mathematics)

## Euler-Lagrange Equation and How to Use it in 5 Easy Steps

Here you will learn what the Euler-Lagrange equation is good for and how to apply it to concrete problems (for example, a thrown particle).
