Resistance

The Characteristics of Electricity

This video explains how the dimensions, nature of material and temperature of a conductor affect its resistance.

Components of a Simple DC Circuit

The Characteristics of Electricity

This video identifies and describes the functions of each component in a simple DC circuit such as the battery, switch, load, fuse and wire.

Methods of Charging an Object

The Characteristics of Electricity

This video explains how charges can redistribute themselves through friction, conduction, induction and polarisation.

Static and Current Electricity

The Characteristics of Electricity

This video describes and explains the differences between static and current electricity. It also looks at static discharge, and how static charge builds up in a thundercloud.

Differences Between Conductors and Insulators

The Characteristics of Electricity

This video explains the differences between conductors and insulators.

Potential Difference

The Characteristics of Electricity

This video defines potential difference and explains how it is measured.

Ohm's Law

The Characteristics of Electricity

This video demonstrates how the electric current that passes through a conductor is directly proportional to the potential difference across its ends.

Electroscope

The Characteristics of Electricity

This video demonstrates how an electroscope can detect and measure the charge of a body.

Conductors and Insulators

The Characteristics of Electricity

This video distinguishes the difference between conductors and insulators, and their importance.

Characteristics of Parallel and Series Circuits

The Characteristics of Electricity

This video describes the characteristics of a parallel circuit and explains how the different components are connected. It also looks at the characteristics of a series circuit.

Ammeter, Voltmeter and Multimeter

The Characteristics of Electricity

This video explains the uses of the ammeter and demonstrates how they must be connected in a circuit. It also describes how a multimeter can measure different electrical quantities (i.e. current and voltage).
Working at Height

Working at Height

Surviving Health and Safety

Being high isn't always a good thing. In fact an inevitable condition of being high is being low again. What goes up, must come down, and if you go from up to down really quickly? Well, thanks to physics, it's going to get messy. Gravity +...Show More
Manual Handling

Manual Handling

Surviving Health and Safety

Being alive is a dangerous business. Every day we literally get closer to the end of the world. Lucky for you, you have made the choice to watch this survival guide on manual handling. So cross your eyes and keep your fingers peeled—it's time...Show More
Future-Focused Structures

Future-Focused Structures

Building by Design

Engineering, construction and structural design have come a long way since humans first got here. This clip looks at modern design and construction materials, and provides glimpses of the future, as technology and our understanding of...Show More
Structures and Stress

Structures and Stress

Building by Design

Human structures must be designed to withstand a range of forces. Here, three types of forces causing stress on structures are highlighted – bending, torsion and shear. Each one is defined, and different construction techniques are examined,...Show More
Structures and Balance

Structures and Balance

Building by Design

A number of different design and structural elements are used in constructions – from the most simple to highly complex. This clip explores three common construction elements – columns, beams and cantilevers – defining each and providing...Show More
Structures and Forces

Structures and Forces

Building by Design

Over millennia, human-built structures have become bigger, more complex and quicker to build. A key to this has been understanding how forces behave. This clip looks at two types of opposing forces – tension and compression – defining them...Show More
Newton's Laws of Motion

Newton's Laws of Motion

Collisions

Newton’s three laws of motion are fundamental to many aspects of physics, including collisions. This clip covers the laws, explaining each and looking at how they apply to different examples of collisions. Calculations involving force, mass,...Show More
Energy Transfers

Energy Transfers

Collisions

Understanding the relationship between different variable quantities when objects collide enables us to explain and predict their behaviour. This clip looks at quantities including work, force, distance, mass, velocity and kinetic energy. Worked...Show More
Applications of Scalar and Vector Quantities

Applications of Scalar and Vector Quantities

Collisions

Calculating scalar and vector quantities is vital to understanding collisions. Using tennis court action, this clip examines various quantities including initial and final velocity, displacement, acceleration and time. A number of clearly worked...Show More
Physics of Collisions

Physics of Collisions

Collisions

Collisions occur around us constantly. To know how objects behave when they collide, an understanding of some important concepts of physics is needed. This clip features many examples of collisions, and examines how applying Newton’s Laws of...Show More
Episode 2: Measuring Energy

Episode 2: Measuring Energy

Shedding Light on Energy

In this episode, we look at the 'joule', the unit for energy. We look at how much energy is stored in different foods by comparing apples and oranges (normally a no-no) and we discuss how much energy we need to do certain things including nothing...Show More
Episode 3: Energy Efficiency

Episode 3: Energy Efficiency

Shedding Light on Energy

In this episode, we introduce students to the concept of efficiency, which is a measure of how much useful energy you get out of something compared to the amount of energy that you put into it. We answer a bunch of questions including: How much...Show More
Episode 1: Forms of Energy

Episode 1: Forms of Energy

Shedding Light on Energy

In Forms of Energy we introduce students to the different types of energy that affect their lives daily and describe how energy can change from one form to another. We also explore one of the most important discoveries ever made.
Episode 7: Newton's Second Law

Episode 7: Newton's Second Law

Shedding Light on Motion

In Newton's Second Law, we answer the most important question that has ever been asked: how does a magician pull a table cloth out from under a dinner set? No, seriously, we look at the simple yet powerful equation 'F=ma'. Newton's Second Law...Show More
