I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us …
Newton’s Laws: Crash Course Physics #5 I’m sure you’ve heard of Isaac Newton and maybe of some of his laws. Like, that thing about “equal and opposite reactions” and such. But what do …
Newton's first law is all about Inertia, which is basically an object's tendency to keep doing what it's doing. It's often stated as: "An object in motion will remain in motion, and an object at rest will remain at rest, unless acted upon by a force.".
And for that we're going to turn to a physicist you've probably heard of: Isaac Newton .#N#With his three laws published in 1687 in his book Principia, Newton outlined his understanding of motion and a lot of his ideas were totally new. Today, more than 300 years later, if you're trying to describe the effects of forces on just about any everyday object , a box on the ground, a reindeer pulling a sleigh or an elevator taking you up to your apartment, then you're going to want to use Newton's laws. And yes, I'll explain the reindeer thing later.#N#[Crash Course Intro plays]
And this idea connects nicely to Newton's second law: "Net force is equal to mass times acceleration.". Or as an equation: (Fnet = ma). It's important to remember that we're talking about net force here, the amount of force left over once you've added together all the forces that might cancel each other out.
This tutorial will expose you to the foundation of classical mechanics--Newton's laws. On one level they are intuitive, on another lever they are completely counter-intuitive. Challenge your take on reality and watch this tutorial. The world will look very different after you're done.

You will often hear physics professors be careful to say "net force" or "unbalanced force" rather than just "force". Why? This tutorial explains why and might give you more intuition about Newton's laws in the process.
This short tutorial will have you dealing with orbiting frozen socks in order to understand whether you understand Newton's Laws. We also quiz you a bit during the videos just to make sure that you aren't daydreaming about what you would do with a frozen sock.
We've all slid down slides/snow-or-mud-covered-hills/railings at some point in our life (if not, you haven't really lived) and noticed that the smoother the surface the more we would accelerate (try to slide down a non-snow-or-mud-covered hill). This tutorial looks into this in some depth.
Bad commute? Baby crying? Bills to pay? Looking to take a bath with some Calgon (do a search on YouTube for context) to ease your tension? This tutorial has nothing (actually little, not nothing) to do with that.
When two or more objects must move with the same magnitude of acceleration (like masses on strings, or boxes pushed into each other), we can treat the entire system as a single object when finding the acceleration.
The three laws of motion as laid out by Sir Isaac Newton are manifested in nearly all activities that go on in everyday life - including car crashes. From a flying bird to a racing car, these laws governing motion are ubiquitous. As a matter of fact, nearly 99% of all activities in our physical world are usually governed by these laws. Newton's Laws of Motion are very important when engineers design airplanes, sports equipment, cars, trains and toys among other motion equipment. In this article, we explain Newton's 3 laws of motion in a car crash.

In other words, objects have a natural tendency to continue doing what they were doing until acted upon. In the absence of an external force, a body in motion will maintain the state of motion that it was in or will continue being in its state of rest. This law is normally referred to as the law of inertia. YouTube.
This law states that action and reaction are equal and opposite. In short, for every action, there will be an equal an opposite reaction. The law is about conservation of energy and also mentions contribution of force.
Essentially, a force is defined as a push or a pull on a certain object and this is due to interaction with that object.

Using seat belts ensures that there are necessary forces to accelerate or even decelerate motion. When a seat belt is not used, the passenger will tend to continue with their state of motion. Thus, they will be propelled from the automobile and then be hurled onto the air.
