Newton's laws/Newtonian physics concepts

The base of all that we know about real-world physics comes from the principles developed by Sir Isaac Newton, also known as Newton's three laws of motion. When we recreate real-world physics in video games, it is very important that we understand these laws and how they affect objects in our game world. Keep in mind that not all games use realistic physics, but these laws of motion are still important to grasp when you develop any game world.

Newton's first law of motion

Isaac Newton's first law of motion, also known as the Law of Inertia, states that every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. In other words, an object in motion ...
