Physics 1 - Newton's First Law

| No Comments | 3 TrackBacks

We've been learning about kinematics with the past few physics videos. But, what if instead of describing how things move, we want to learn why they move they way they do? That's where we start looking at dynamics. Dynamics is the description of motion and the forces that cause it. While Galileo initially started the process of thinking about motion, Isaac Newton really was the first to understand the prime ideas of dynamics. It's because of this understanding that he was able to develop his ideas into what are now considered laws of motion. In today's free Physics 1 video, we're going to learn about Newton's First Law. Many of you have heard it before. An object at rest remains at rest and an object in motion stays in motion unless acted upon by an external unbalanced force. A force is nothing more than a push or a pull and what Newton's First Law is telling us is if you don't push on something, then it's not going to change its motion. Check out today's video to learn more and see some examples of Newton's Law in action.

Newton's laws are key to understanding motion and how forces on an object can impact its motion. So far all the laws have been about a single object and the impact of outside forces upon it. With the first law, Newton showed that a body in motion remai... Read More
