Nanoparticles

Nanoparticles are tiny bits of material with a diameter between one and 100 nanometres. This clip explores the tiny world of nanoparticles and how their size and structure make them so useful, including the square-cube law and the relationship...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

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
Episode 8: Newton's Third Law

Episode 8: Newton's Third Law

Shedding Light on Motion

In Newton's Third Law, we look at that most poetic of all Laws: For every action there is an equal and opposite reaction. How does a rocket engine work? Why do guns recoil when fired? How do our muscles work? What propels us when we're swimming?...Show More
Episode 6: Newton's First Law

Episode 6: Newton's First Law

Shedding Light on Motion

In Newton's First Law, presenter Spiro Liacos is 'thrown forward' in a head-on collision, 'thrown backwards' when his tram takes off, and 'thrown to the side' when his car suddely turns a corner. But in fact none of these things actually happen!...Show More
Orbits of Satellites

Orbits of Satellites

Gravity and Motion

Constant unbalanced forces, known as centripetal forces, cause planets, moons and stars in the universe to orbit one another. This clip, aimed at senior level students of physics, examines fundamental aspects of orbital motion of satellites in...Show More
Energy of Orbital Systems

Energy of Orbital Systems

Gravity and Motion

Orbital motion of satellites can be explained mathematically, but orbits – both of natural and artificial satellites – do not always remain constant. This clip examines escape velocity and energy of orbital systems, including gravitational...Show More
Newton's Laws of Gravitation and Motion

Newton's Laws of Gravitation and Motion

Gravity and Motion

Three hundred years ago Sir Isaac Newton’s work paved the way for our understanding of the force of gravity. This clip explains, both qualitatively and quantitatively, the law of gravitation, and how Newton’s second and third laws of motion...Show More
Waves and Sound

Waves and Sound

How do sound or light reach us? What makes a whistle sound so different from a trombone? In this video we will discover what are waves, how they are transmitted and what are their properties. Using sound waves, we will also learn how to recognise...Show More
Episode 5: Graphing Free Fall

Episode 5: Graphing Free Fall

Shedding Light on Motion

In Graphing Free Fall, we continue looking at graphs but pay particular attention to how graphs help us to understand the motion of objects that are either falling straight down or which have been launched vertically upwards into the air.
Episode 4: Graphing Motion

Episode 4: Graphing Motion

Shedding Light on Motion

In a 100-metre sprint, when do athletes reach their highest speed? When do they accelerate at the highest rate and at what point, if any, do they stop accelerating? In Graphing Motion, we look at how graphs can help us better understand the...Show More
Episode 2: Acceleration

Episode 2: Acceleration

Shedding Light on Motion

In this episode, we introduce students to the concept that acceleration is a measure of how quickly something changes its speed. We join James Bond as he falls out of an aeroplane without a paracute, splash into the water at 50.4 km/hr with...Show More
Conduction

Conduction

Flow of Heat

This video introduces students to conduction. Conduction is the process by which heat energy is transmitted through collisions between neighbouring molecules without the molecules moving from a hot region to a cold region.
Ways to Minimise and Increase Friction

Ways to Minimise and Increase Friction

Friction

Depending on whether the presence of friction is advantageous or disadvantageous, there are a variety of methods used to either decrease or increase friction. Friction can be decreased using lubrication, polishing surfaces, or streamlining...Show More
Advantages and Disadvantages of Friction

Advantages and Disadvantages of Friction

Friction

Friction is an important force in our world and has many advantages and disadvantages. Friction is essential for activities such as writing, driving, and walk, but it also causes damage through wear and tear, wastes energy, and generates heat.
Causes of Friction

Causes of Friction

Friction

Frictional force comes into play when an object moves across a surface and always opposes motion. This force occurs due to irregularities on the object and surface interlocking.
Frictional Force

Frictional Force

Friction

Students will learn about friction in this video. Frictional force is a force that slows down moving objects or prevents stationary objects from moving. It acts between a pair of surfaces in contact and in the direction opposite to the force applied.
