SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

In this video, we learn about the importance of units in measuring and estimating different items in our day-to-day life. The video explains how different units are used for measuring liquids, solids, and small quantities of medicines....

To operate and function efficiently, machines of all shapes and sizes need a source of energy. A series of innovations is helping to make energy conversion within fuel cells as efficient as possible.

This video discusses the concept of electromagnetic induction. The video highlights the factors that affect the size and direction of the induced potential difference. The generator effect is explained, and it is noted that the induced...

Late Friday night, almost 50 students from Maryland and Virginia arrived at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for a STEM-themed sleepover, ready to learn about careers in science, technology,...

Einstein predicted gravity waves in his general theory of relativity, but to date these ripples in the fabric of space-time have never been observed. Now a scientific research technique called Atomic Interferometry is trying to...

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

The speech is taken from the 'Anabasis of Alexander' (Book VII Chapter X), written around 130 AD by the Roman/Greek historian Arrian. Arrian had access to eyewitness accounts which are now lost (principally Ptolemy and Nearchus), and...

Given certain parameters, how would solve the first part of this given problem?<br/>
Equations Of Motion In One Dimension, Part 3

Given certain parameters, how would solve the second part of this given problem?<br/>
Equations Of Motion In One Dimension, Part 4

Mr. Fullerton of APlusPhysics.com makes a guest appearance as a floating head to help us learn about Elastic Potential Energy. Several examples of objects which store elastic potential energy are shown and one example of stored elastic...

Metric system.

What are the formulas of predictor equations? What do each equation mean?<br/>
Equations Of Motion In One Dimension, Part 1

In this video, we explain how to determine whether you need to find the area, surface area, or volume of an object by looking at their definitions. We review the concepts of area, surface area, and volume, and provides examples of how to...

What is the formula to calculate the volume of a cone? Given the radius and height, how do you calculate the volume of a cone? <br/>
Cylinders, Cones and Spheres, Part 4

How does physics define power? How would you write the concept of power? In some situations, why use horsepower instead of watt?<br/>
Physics Power, Part 1

In their first adventure, the SI Superheroes (aka the International League of Measurement Units) use the power of measurement to help a stranded soccer player get home.

You sent us your nano questions, and we answered! In this Ask a Scientist – Nano Edition, we join nano expert Lisa Friedersdorf, from the National Nanotechnology Coordination Office.

Given certain parameters, how would solve this given problem?<br/>
Equations Of Motion In One Dimension, Part 2

This is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when...

This program introduces students to the usefulness and fun of the metric system. The concept of measurement as related to the metric system kicks off the video, followed by examples of how the metric system is used in science. Through a...

In this video, we calculate the volume of a cone [with example].

There are two kinds of electrical circuits, series and parallel. Components that are connected one after another on the same loop of the circuit are connected in series. If one lamp were to break in a series circuit, all the lamps would...

The metric system is an internationally agreed upon convention for measuring distance, time, volume, and other quantifiable measurements. Learn about the benefits of the metric system and the importance of a universally recognized system...
