This video provides an explanation of the differences between contact forces and non-contact forces, with a particular focus on the force of gravity. The speaker defines what a force is and how it interacts with objects. They provide...

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt breaks down Isaac Newton's Third Law of...

Understanding Newton’s Universal Law of Gravitation. Including a dramatization of The Cavendish Experiment and force visualization via qualitative examples.

The resultant force vector is the vector sum of all other external forces. This can be found graphically by placing the arrows on top of each other or analytically by summing up all horizontal and vertical components.

Think of a spanner loosening a fixed nut, or a child on a seesaw, or a door opening around a fixed hinge. All of these things are connected by something called moments… A moment is the turning force around a fixed pivot. The pivot is the...

One way to find the shear force V and bending moment M in a beam is by using calculus<b<br/>r/><b<br/>r/>;

dV/dx = - w

dM/dx = V

A Level Physics - Doodle Science teaches you high school and College physics in a less boring way in almost no time!

This video explains the motor effect, which occurs when a current-carrying conductor is placed in a magnetic field, creating a force between the conductor and the magnet. The video discusses how to calculate the magnitude and direction...

This video explains the concept of work and energy transfer when a force is used to displace an object. The video demonstrates how to calculate work done and the energy transferred in different situations. The video provides examples...

Three major differences between weight and mass are discussed and three media examples of weight in kilograms are presented (and you should know that weight is NOT in kilograms).

You had a baby! Hooray! Now it's time to stop building ramps and pulleys and it's time to start building baby stuff. You love astronomy so you decide to make a mobile of the solar system. But in order to get everything to balance out, we...

The gravitational field is introduced and illustrated. For a constant field and a non-constant field around a spherical object.

Explain how to add and subtract vectors. What is a newton?<br/>
Scalers and Vectors, Part 2

Work is the amount of energy transferred when a force moves something. For example when you carry something upstairs or a lift a heavy object, work is being done. You can calculate the amount of work being done by knowing the force...

This video explains how to calculate the magnitude of the force acting on a conducting wire when it is placed in a magnetic field. The video starts by explaining the motor effect and how a current carrying conductor experiences a force...

Hydraulics might sound complicated but all they are, is another force multiplier. They utilise the fact that liquids are virtually incompressible, which means when you compress them, the pressure you apply to one point of the liquid is...

Learn about and see examples of Translational Equilibrium.

In this video we explore what factors affect the size of the force on a wire carrying an electric current when it is placed in a magnetic field.

Derive the acceleration due to gravity on any planet. Find the acceleration due to gravity on Mt. Everest. And determine how much higher you could jump on the top of Mt. Everest!

The video explains an experiment to investigate the relationship between the extension of a spring and the force applied to it. The procedure for the experiment is described step-by-step, including how to measure the extension and how to...

All is quiet inside the anthropology and archaeology museum… until Carmen strikes again! This lesson will apply Newton’s 2nd Law of Motion to moving and accelerating objects.

Definitions included: Newton’s 2nd Law of Motion,...

This video is a lecture on Newton's Second Law, which explains the relationship between the acceleration of an object and the resultant force applied to it. The definition of acceleration is discussed, and it is demonstrated how...

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt breaks down Isaac Newton's Second Law of...

A very basic introduction to the rotational form of Newton’s Second Law of Motion by way of its translational form.
