Electric Force
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).

Gravitation: The Four Fundamental Forces of Physics #3
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...

Gravitational Force
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 of...

Vector Sum of Forces
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.

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...

Newton's Third Law
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...

Impulse
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...

PS2A - Forces and Motion
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...

How to Calculate Force - Newton's 2nd Law of Motion
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...
