The police can’t contain Carmen! Will Vector Man step in to save the day? This lesson will apply Newton’s 3rd Law of Motion and identify action-reaction pairs. Definitions included: Newton’s 3rd Law of Motion Misconceptions included: a car engine pushes a car forwards, friction always hinders motion, a bigger/stronger object exerts more force than a smaller/weaker object Equations: Newton’s 3rd Law of Motion Show Less

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, proportional (directly proportional), inversely proportional, proportionality constant. Misconceptions included: every force causes acceleration, force is equal to mass times acceleration. Equations: Newton’s 2nd Law of Motion Show Less

It’s no surprise that forces are everywhere! But how do we work out which forces are important, and which ones can be ignored? This lesson will distinguish between external and internal forces, before diving into more examples of contact forces. Definitions included: system, external force, internal force, compression, tension, shear, normal force, tension force, elastic force, ideal object Show Less

Vector Man rescues someone who is having a heart attack! But he doesn’t take them to the hospital… This lesson will apply Newton’s 1st Law of Motion to stationary, moving and accelerating objects. Definitions included: net external force, translational equilibrium, static equilibrium, dynamic equilibrium, Newton’s 1st Law of Motion. Misconceptions included: objects only move when acted upon by a force, when the force is removed the object returns to its natural state of rest, there are no forces acting on a stationary object, only active forces exist, passive forces do not exist. Show Less

Forces are like friends… some are real and some are fake! This lesson will distinguish between real and fictitious forces. Definitions included: frame of reference, inertial frame of reference, non-inertial frame of reference, real force, fictitious force (pseudo force), centripetal force, centrifugal force, coriolis force Misconceptions included: when a car brakes the seat pushes the passenger forwards, circular motion is caused by the centrifugal force Show Less

Lotus isn’t the only one who has noticed that Ian is up to something… This lesson will explain how dynamic friction is dependent on the normal force and roughness of a surface, but independent of speed and apparent contact area. Definitions included: dynamic friction (kinetic friction), coefficient of dynamic friction Equations included: dynamic friction Misconceptions included: an object only moves when acted upon by a force, when the force is removed the object returns to its natural state of rest, friction is always bad Show Less

A birthday party isn’t complete without cake, music and drama! This lesson will introduce the most common types of contact forces encountered in Physics. Definitions included: contact force, normal force, friction force, static friction, dynamic friction (kinetic friction), ground reaction force, rolling resistance, drag force, lift force, buoyancy force. Misconceptions included: the normal force always opposes the weight force, objects that sink do not experience a buoyancy force. Show Less

Lotus and Brooke put their skills to the test, but the game is rigged! This lesson will use Hooke’s Law to calculate the extension of a spring when a force is applied. Definitions included: elastic force, Hooke’s Law, force-displacement graph, proportionality limit (limit of proportionality) Equations included: Hooke’s Law Show Less

Lotus uses her birthday present to uncover another secret about Mark Brent - he’s radioactive! This lesson will introduce the different types of field forces. Definitions included: force, field force, mass, weight, electric force, magnetic force, weak nuclear force, strong nuclear force. Misconceptions included: mass is the same as weight. Equations: weight Show Less

Although the impromptu surgery was a success, Shannon is taken to the hospital. This lesson will define inertia and apply Newton’s Law of Inertia. Definitions included: inertia Misconceptions included: inertia is a force, objects only move when acted upon by a force, when the force is removed the object returns to its natural state of rest, it takes a larger force to move a heavier object. Show Less

Smart devices have become an integral part of our everyday lives, which means that chips are everywhere. But what happens when there is a global shortage of chips? This video explains how the global supply chain can falter as a result of pandemics and wars, resulting in events such as Chipageddon. Informative and engaging, this is an essential resource for Economics classrooms in today’s rapidly changing world. Show Less

Today, the practice of trading goods and services with other people exists on a planetary scale: the global supply chain. This video explains how various consumer goods, from planes to phones, rely on globalisation, the notion of planned obsolescence and how quickly the global supply chain can falter. Informative and engaging, this is an essential resource for Economics classrooms in today’s rapidly changing world. Show Less

In Acids in Industry, we look at what acids are, how they're made, and how they're used in steel making and agriculture. We also take a quick trip back to the 1770s to look at how acids were used by Captain James Cook to save his crew from the disease that killed more sailors than shipwrecks and sea battles! Show Less

Cities are one of our greatest inventions, they bring us together and drive wealth - but as more of us flock to live and work in them, we need to find ways to make them greener, more sustainable and efficient places to live. Physicist Dr Niraj Lal explores some of the engineering solutions driving change. To see how we’ll keep our growing population moving he visits the construction site of the largest public transport system ever undertaken nationally and discovers how engineers are finding ways to replace concrete - one of the biggest CO2 emitters in the world – with greener alternatives.
