In this video Paul Andersen describes the relationship between energy and forces. When objects are directly touching electromagnetic forces can result in forces and energy exchange. When objects are not directly touching fields;...

Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

In this video Paul Andersen explains how the vector sum of forces can be used to identify the net force on an object. The net force can be used to determine the overall acceleration of the object using Newton's Second Law.

In this video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a system the...

In this video Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action) and equal and opposite force (Reaction) is applied to the original object. Several scenarios...

In this video Paul Andersen explains how contact forces result from interatomic forces. The following forces are explained at the interatomic level: normal force, applied force, friction force, tension force, spring force, and buoyant...

This content presents a solved physics problem that calculates the frictional force and acceleration of a 3.5 kg block pushed along a horizontal floor by a 15 N force at a 40° angle to the horizontal. It demonstrates the application of...

Understand the four key types of forces—gravitational, normal, frictional, and tension—and how they affect motion. Learn to classify, analyze, and apply these forces to solve mechanics problems

Given certain parameters, how would you solve this problem in X direction?<br/>
Newton's Laws Of Motion With Friction, Part 3

Static Friction Summary

In this video, the sport of Hammer throw is explained and how physics plays a crucial role in achieving a long-distance throw. The concept of centripetal force and how it affects circular motion is discussed with the help of an...

Newton's Laws Of Motion With Friction, Part 4

This video explains the physics of how wheelies work!

Lisa, are you serious? Alright, just one more favor. This one is a little trickier than the previous, because there is some trigonometry involved, beyond the kinematics and friction from the previous problems. What will become of your...

Given certain parameters, how would you solve this problem in Y direction?<br/>
Newton's Laws Of Motion With Friction, Part 2

You're really getting good at building physics toys in your garage! Check this awesome pulley system. You put your physics knowledge to the test and try to make a prediction about what will happen when you let these two blocks go. Will...

Lisa is moving again already! I dunno, I think there were bedbugs. This time you have a different plan, but you will still need kinematics and Newton's laws to find out how much time and effort stand between you and more snacks. Give it...

What is friction? What are the two types of frictional forces?<br/>
Newton's Laws Of Motion With Friction, Part 1

This is a lecture video on Newton's third law that discusses the forces that act between two interacting objects. The speaker provides several examples, including a man sitting on a chair, a cannon firing a cannonball, a fish swimming...

It explains the types of friction, namely static, rolling, sliding and fluid friction.

Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn...

Since the first curling rock curved around the first guard, there have been questions about the strange physics that give the game its name. Why exactly does a curling rock curl, instead of sliding in a straight line? The CBC’s “Physics...
