In this video we will look at how force, mass, velocity and acceleration are all related. Remember that velocity is the speed in a particular direction - a vector quantity! To change the velocity of an object there needs to be a force...

Defining the Force of Gravity or Weight and Gravitational Mass. We also determine the dimensions for force in both Metric and English units.

When a point particle collides with a rigid object with shape which is allowed to rotate on a stationary axis, is linear momentum of the system conserved? Is angular momentum of the system conserved? These questions are answered using...

What's work? Not that place you go to earn money. In physics it means something else. And what's energy? Not like in the groovy sense. Actually, energy is one of the most improperly used words in the English language. Let physics define...

In this video you will about weight, force, mass and gravity. When it says 56 kilograms on your bathroom scales, what are you actually measuring? Well, if you said weight, like most people would, then you are sort-of wrong! Kilograms are...

Please do not confuse the Coefficient of Friction with the Force of Friction. This video will help you not fall into that Pit of Despair!

Learn why a centripetal force exists, three important things to remember about centripetal force, and drawing free body diagrams for objects moving in circles.

This begins by introducing the concept of gravity and how it affects objects. It then delves into Isaac Newton's early life, including his difficult upbringing and his passion for science. The video highlights his education, his...

This live-action video program is about the word Gravitational Force. The program is designed to reinforce and support a student's comprehension and retention of the word Gravitational Force through use of video footage, photographs,...

Calculus based review of conservation of momentum, the momentum version of Newton’s second law, the Impulse-Momentum Theorem, impulse approximation, impact force, elastic, inelastic and perfectly inelastic collisions, position, velocity...

Learn about Newton’s First Law of Motion with two examples shown. Plus, I snuck in some free body diagrams and subtle hints at Newton’s Second and Third Laws as well. Thank you so much to Mrs. Zeller for being a Flipping Physics...

This live-action video program is about the word newton. The program is designed to reinforce and support a student's comprehension and retention of the word newton through use of video footage, photographs, diagrams and colorful,...

You thought we were all done with Newton, didn't you? You figured that three laws are enough for any scientist. Well think again! Newton was quite the champ, and his work with gravity was revolutionary. I mean, the guy invented calculus...
