In this program 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 number of questions including: how much light energy do we get out of light globes compared to
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.
In Measuring Energy, we introduce students to 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 con
In this program 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.
In this program host 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 suddenly turns a corner. But in fact none of these things actually happen. Using excellent visuals, this program looks at the fact that an
In a 100-meter 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 this program we look at how graphs can help us better understand the motion of athletes and cars.
Introduces students to the concept that the movement of an object is always relative to something else. We call it “sunrise” but is it really? Can we stand still and move around from place to place at the same time? If a car is moving forwards, can it also be moving backwards at the same time? Can
In Newton’s Second Law, we answer the most important question that has ever been asked - how does a magician pull a tablecloth out from under a dinner table? We look at the simple and yet powerful equation Fnet = ma. Newton’s Second Law tells us how to calculate the amount of force required to acc
