What is Newton's 1st Law (the law of inertia)?

In this tutorial you will learn about Newton's 1st Law, which is also called the Law of Inertia.

Summary

  1. If nothing provides a push or a pull, then objects at rest stay at rest, and objects in motion stay in motion

Notes

    1. An object at rest has zero velocity
    1. v with an arrow- velocity vector
    1. The object in motion maintains a constant velocity
    1. v with an arrow- velocity vector
    2. m- meters
    3. s-seconds
    1. But imagine a car that has a force acting on it
    1. A force acting on an object will change the object's velocity
    1. Friction opposes motion
