### Basic Physics: Force and Friction

Friction is a force, and from physics, you know that forces can change an object's speed or direction. The force of friction from dry pavement on your car's tires is much greater than the force of friction

### Physics: Transforming Energy between Kinetic and Potential Forms

The law of conservation of energy is one of the most important ideas in science. It states that energy can be transferred or transformed but never created or destroyed. But what is this thing that can

### Physics: Transforming Energy between Mechanical and Thermal Forms

Thermodynamics is the study of how thermal energy (heat energy) and mechanical energy are related. It's an important topic in physics as well as in engineering. Engineers must employ thermodynamic principles

### Physics: Applying Forces between Magnets and Electricity

You've probably seen an electromagnet in action. This is a coil of current-carrying wire that acts like a magnet. But why does this happen? And how are electricity and magnetism related? To understand

### Physics I Workbook For Dummies Cheat Sheet

Avoid difficulties when working on physics by knowing the common issues that can cause trouble in physics problems, understanding physical constants, and grasping principal physics equations.

### 10 Important Ideas in Physics

Physics is the scientific study of the basic rules that govern the universe. Because physicists like to be precise, they often express their ideas as mathematical equations. What follow are ten of the
