Energy skate park: basics

This is an interactive teaching and learning resource that years 7 to 10 secondary school students can use to simulate the motion of a skateboarder descending and ascending on a variety of tracks. Height, speed and energy conservation are visually displayed. The skater's mass and starting height, as well as the drag he ...

Measuring Speed (Simulation)

Students use this resource consisting of a webpage with diagrams of three cars that students can vary the speed at which they are travelling. They can calculate the time to travel 3000m and then observe the cars as they travel the distance. This demonstrates how to work out the speed of a moving object and how to make calculations ...

Catalyst: Applying trigonometry: leaning tower

The Leaning Tower of Gingin is the centrepiece of the Gravity Discovery Centre. The Catalyst team of Derek, Simon and Anja drop watermelons from the tower, to examine the rate at which they fall. They are testing Galileo's theory about falling objects. The dimensions of the tower provide an opportunity to apply some basic ...

Experimentals: Do different things fall faster?

Want to find out what happens when you drop a watermelon and an apple from the top of a building? In this clip, Bernie Hobbs and Ruben Meerman, investigate whether the mass of an object influences how fast it falls. Bernie and Ruben ride the 'Giant Drop' at Dreamworld, drop a watermelon and apple from an eighth floor balcony, ...

Experimentals: Examples of Bernoulli's theorem

Have you ever wondered how a yacht sails into the wind? Watch as the Experimentals team works through practical demonstrations of Bernoulli's theorem. You're in for a few surprises as you learn how gases and liquids change their behavior as they begin to flow.

Meet the BFFs: Four fundamental forces

We all know something about gravity, but what about the other fundamental forces of physics? Explore the properties of two familiar forces experienced in daily life, and of two less familiar ones. How do they interact, and what keeps everything from falling apart? This video was Kate Dent's entry into the 2013 Sleek Geeks ...

Catalyst: Do heavier things fall faster?

Will a medicine ball or a basketball hit the ground first when dropped at the same time from the same height? In this clip, Catalyst's Dr Derek Muller investigates what influences the speed at which objects fall. Derek challenges some people in a market to make a prediction and explain their thinking, before he finally ...

Measuring gravity

Did you know you can measure gravity? The more mass an object has, the more gravity it has, so by measuring the mass of something, you can figure out its gravity. Why do you think climate scientists may want these measurements? Watch this NASA animation to find out.

Projectile motion

This is an interactive resource about projectile motion. Students use a simulation of a cannon to fire various objects. They can set the firing angle, initial speed, height and mass, with or without air resistance. Students are encouraged to make a game out of this simulation by trying to hit a target. This interactive ...

Energy skate park

This is an interactive resource about the potential and kinetic energy changes as a skater rolls around a skate park. Students learn about conservation of energy with a skater, they can build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. Students can also ...
