In this video Paul Andersen explains how electric force on an object inside a field can be calculated by multiplying the charge of the object (in C) times the electric field strength (in N/C).

Hank continues our series on the four fundamental forces of physics with a description of gravitation -the interaction by which physical bodies attract with a force proportional to that of their masses, and which is responsible for...

In this video Paul Andersen explains how an object with mass placed in a gravitational field experiences a gravitational force. On the Earth this gravitational force is known as weight. The gravitational force is equal to the product...

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 defines impulse as the product of the force applied and the time over which the force is applied. The impulse of an object is equivalent to the change in momentum of the object. Several problems related to...

Moving on to our unit on the Physics of Electricity, it's time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean? In this episode, Shini talks about electrostatic forces, electrical...

Paul Andersen introduces forces, motion, and Newton's three laws in this video. He begins by describing forces as pushes or pulls on objects that produce motion. A lack of motion results from a balanced set of forces. A teaching...

Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.

This video discusses Newton's first law of motion, also known as the law of inertia. It explains how Newton built upon the experiments of Galileo to formulate this law. The video illustrates the concept using the example of a ball on the...

Newton's 2nd Law tells explains how force can affect the acceleration of an object. The more force you apply to an object, the more it will accelerate. Also, the more mass an object has, the more force that is needed to cause the object...

Work is the transfer of energy to or from an object that causes the object to move. Energy is required to do this so when you do work, you are just transferring energy from yourself to the object you are moving. In this video we will...

We make a Cartesian diver using a drinking straw and sticky tack. When the diver is placed in a sealed bottle of water it can be controlled by squeezing and releasing the bottle, which makes it rise and fall within the water. Physics -...

We use eggs to show how different rates of deceleration affect the outcome of collisions. One egg is dropped onto a hard surface and breaks. The second egg is dropped onto a soft surface and bounces, as the material slows its...
