Areas of classical physics. Mechanics (how levers help lift things, cars keep moving after the engine is turned off, etc.) Thermodynamics (why we experience some things as hot and other things as cold, why it takes longer to heat water than air, etc.) Electricity (why rubbing one object with another can produce a static charge, why electrons ...
Classical physics. Classical physics are the physics that were made before the 20th century. This part of physics studies things like movement, light, gravity, and electricity. Most of physics today uses ideas that are more complicated than the ideas of classical physics, because in the 20th century, physicists discovered two better ways to ...

- What is G-ForceA G force is when you feel your same weight against you. for example a roller coaster is 2 Gs,which means you will feel 2x your weight which ever d...
- Does the study of physics alter what we discover in mathematics?For sure. Newton invented calculus to solve the specific problem of calculating planetary motion. Bessel functions were invented to solve the spher...

- Can Newton’s 1st and 2nd law of motion both be active at the same time?Sure. Newton's first law states that an object at rest or moving with a constant velocity will stay at rest or stay moving with a constant velocity...
- why is there no gravity in space? and why do we have gravity?There actually is gravity in space: the whole reason the Earth orbits around the sun is because the sun is a 'heavy' object that makes an impressio...
Classical physics is considered the limit of quantum mechanics for a large number of particles. On the other hand, classic mechanics is derived from relativistic mechanics. For example, in many formulations from special relativity, a correction factor (v/c) 2 appears, where v is the velocity of the object and c is the speed of light.
