• Newton's Third Law
Saturday, November 21
2:00 pm on UEN-TV 9.1
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 they're 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 program.
• Newton's Second Law
Saturday, November 14
2:00 pm on UEN-TV 9.1
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 set? No, seriously, we look at the so simple and yet so powerful equation Fnet = ma. Newton's Second Law tells us how to calculate the amount of force required to accelerate something by a given amount.
• Newton's First Law
Saturday, November 7
2:00 pm on UEN-TV 9.1
In this program 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 suddenly turns a corner. But in fact none of these things actually happen! Using brilliant visuals, this program 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.
• Graphing Free Fall
Saturday, October 31
2:00 pm on UEN-TV 9.1
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.
• Graphing Motion
Saturday, October 24
2:00 pm on UEN-TV 9.1
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 this program we look at how graphs can help us better understand the motion of athletes and of cars and other things.
• Relative Motion
Saturday, October 17
2:00 pm on UEN-TV 9.1
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? And can we throw a single ball towards the left and towards the right at the same time? The answers to all these questions will be answered and along the way we will gain a much deeper understanding of velocity and acceleration!
• Acceleration
Saturday, October 10
2:00 pm on UEN-TV 9.1
Introduces 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 parachute, splash into the water at 50.4 km/hr with presenter Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.
• Speed
Saturday, October 3
2:00 pm on UEN-TV 9.1
Introduces students to the concept that speed is a measure of how far something travels in a given amount of time, looks at how speed varies in a sprint, explains the concept of velocity, and demonstrates a number of ways of measuring an object's speed.
