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, acceleration and stopping time are applied to various scenarios. It is an excellent learning resource for senior level physics students. Show Less

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 examples using different mathematical formulae are applied to everyday examples of collisions. It is a great learning resource for senior level physics students. Show Less

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 examples using a range of mathematical formulae are provided, which will assist senior level physics students to understand the relationship between various scalar and vector quantities.

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 Motion, principles of energy and measuring variable quantities enable us to understand and predict the behaviour of colliding objects. It is an ideal resource for senior level physics students. Show Less

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 much at all. We then explore the concept of energy balance and reveal the two simple rules for weight loss. That's right, these are only two! Show Less

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 light energy we get out of light globes compared to the amount of electrical energy that goes into them (Hint: it’s not much; they should be called heat globes!), how much kinetic energy we get out of cars compared to the amount of chemical energy that we put into them (Hint: it’s a bit more, but not that much more!), and how our arched feet make us the long-distance running champions of the animal world. This video is the most energy-efficient way of learning everything that you need to know about energy efficiency! Show Less

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 tells us how to calculate the amount of force required to accelerat somthing by a given amount. Show Less

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? And how exactly is gravity a two-way interaction? All these questions, and many more, will be answered in this excellent video.

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! Using brilliant visuals, this episode looks at the fact that an object will remain stationary or move with a constant velocity unless a force acts on it. It also describes a number of different forces that affect our lives daily. Show Less

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 motion of athletes, cars, and other things. Show Less

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 present Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.

Pre-operational checks help to ensure that the backhoe is safe to use by identifying damage and helping to prevent accidents. This workplace safety training video snippet shows a suggested process for a licensed backhoe operator to conduct pre-operational checks. Show Less

Portable ladders are used to provide access for light work tasks above ground level. Using ladders can be hazardous with falls from ladders being a common cause of workplace injury. The risk of falls is commonly caused by over-reaching, trying to carry out heavy tasks or not securing a ladder adequately. This safety training video snippet demonstrates steps to securely set up both a step ladder and a small stair ladder, getting on and off the ladders and working on them safely. Show Less

The risk of falls is commonly caused by over-reaching, trying to carry out heavy tasks or not securing a ladder adequately. This safety training video snippet demonstrates steps to securely set up a platform ladder, getting on and off the ladder and working on it safely. Show Less
