Overview
Whenever one body exerts a force on a second body, the first body experiences a force equal in magnitude and opposite in direction, to the force that it exerts. For instance, when a person pushes on a wall, the wall exerts an equal and opposite force towards the person. This brings us to Newton's third law of motion. Newton's third law represents a certain symmetry in nature: Forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself. This law is sometimes loosely referred to as "action-reaction," where the force exerted is the action and the force experienced as a consequence is the reaction. Newton's third law has practical uses in analyzing the origin of forces and understanding which forces are external to a system.…

Embed code vs URL
An embed code allows you to place a JoVE video directly inside of your learning or training environment. Most learning management systems such as Canvas, Blackboard, and Moodle require an embed code for JoVE content to stream.
A URL allows you to place a link in programs such as PowerPoint or Microsoft Word which takes a user to a separate page where they can watch a JoVE video.
Most of the time, you will want to use the embed code. However, there are some environments that don’t support embed codes such as Google Classrooms and MS Teams. In those instances, you can use a URL to still provide access to JoVE videos.
What is an Embed Code?
Basically, it’s a snippet of code that you put on your website that displays as a video. An embed code pulls the video from the original source, allowing you to display a video without having to host the file on your website.
How to embed a video
STEP 1: COPY YOUR EMBED CODE
To generate the embed code, simply click the Copy button above. You can customize it by choosing a specific language for the video, or setting exact dimensions for the video player.
STEP 2: PASTE THE EMBED CODE INTO YOUR ENVIRONMENT
Embed codes can be used in most learning management systems (Canvas, Blackboard, Moodle…), organizational websites, and a host of other tools. The specifics of how to add in an embed code will depend on your environment.
Generally, it involves accessing a text editor, entering the HTML mode on the editor, and pasting in the embed code. Get more details on embedding into specific environments here.
