### Simple harmonic motion

This collection of six digital curriculum resources includes resources that develop the theoretical and practical aspects of simple harmonic motion (SHM). Video sequences illustrate the fundamental kinematic principles of SHM and reference web pages provide background material on the mathematical techniques required, including ...

### Constant acceleration

Learn to use your knowledge of graphs and calculus to analyse the way things move. Follow the derivation of equations to describe the position, velocity and acceleration of a moving object. Deal conceptually with both positive and negative accelerations. This resource consists of a video in three sections with animations ...

### Projectiles

Learn to analyse the motion of an object that is projected into the air. Look at the vertical and horizontal components of the motion. Discover how the range of a projectile depends on the angle of projection. This resource consists of a video in five sections with a supporting web page containing background material.

### Simple harmonic motion

Use your knowledge of calculus and circular motion to analyse back-and-forth motion. Discover how the position, velocity and acceleration vary, but are closely related. Learn how to apply the theory to vibrating objects such as pendulums and loudspeakers. This resource consists of a video in four sections with a supporting ...

### Why do astronauts float in space?

Have you wondered what it would be like to be an astronaut floating around in the International Space Station? In this clip, Catalyst's Dr Derek Muller investigates what causes this weightlessness in space. Derek challenges some people visiting the Powerhouse Museum in Sydney to explain why they think astronauts float. ...

### Meteorites, asteroids, orbiting and gravity

Learn how Galileo Galilei's work overturned Aristotle's ideas about falling objects and led to an understanding that Earth revolves around the sun. Find out how Isaac Newton showed that the laws of motion on Earth and in space are the same, and that he discovered that the gravitational force of attraction between any two ...

### An eclipse of the Moon

The phases of the Moon and lunar eclipses occur due to the Moon's orbit of Earth, and its position in relation to both the Earth and the Sun. Watch this animation showing a model of the Moon's orbit, its phases and a lunar eclipse. Discover what a total lunar eclipse is and what causes the red colour of a 'blood moon'.

### EagleCat: motion graphs

Investigate distance–time and velocity–time graphs by changing position, speed and acceleration.

### Circular motion

This collection includes six digital curriculum resources that develop the theoretical and practical aspects of circular motion. Video sequences illustrate the fundamental kinematic principles of circular motion. Reference web pages and learning objects provide background material on the mathematical techniques required, ...

### Constant acceleration

This collection includes seven digital curriculum resources that develop the theoretical aspects of kinematics and equations of motion. Video sequences illustrate fundamental principles while reference web pages and learning objects provide background material on the mathematical techniques required, including calculus ...

### Newton’s laws

This collection of nine digital curriculum resources examines forces and their effects. Video sequences develop the theoretical and practical aspects of Newton's three laws of motion, weight, friction, the normal force and centre of mass. Web pages provide background material as well as explaining frames of reference and ...

### Circular motion

Learn to use your knowledge of calculus and vectors to analyse circular motion. Follow the derivation of equations to describe angular velocity and centripetal acceleration. Discover how fast a vehicle has to travel over a hill to lose contact with the road. This resource consists of a video in four sections with a supporting ...

### Newton’s laws

Learn about the effect of unbalanced forces on the motion of objects. Discover why the force of friction delayed the scientific study of motion and how Galileo made an important breakthrough. View demonstrations of Newton's three laws of motion. Analyse real-life situations to find the various forces acting and their effects. ...

### NASA: Eyes Eclipse 2017

This interactive 3D simulation of the total eclipse of August 21st, 2017 enables users to navigate to different locations to watch a simulation of what the eclipse would look like from that area from start to finish. The simulation is available as a web and desktop applications suitable for most devices.

### Looking to the Moon

Use these tasks and resources to investigate how the Earth rotates and how its rotation affects what we see in the sky, in particular the views of the moon. Students explore the relative position and rotation of the moon to the Earth and use this to investigate why we only see one side of the moon.

### Backyard Science: forces

This resource, including student videos, provide opportunities for students to identify types of forces, determine whether forces are balanced or unbalanced and compare water and air resistance. They will conduct an investigation into the relationship between friction and different types of surfaces. Students will design, ...

### Pushing and pulling

Move animals from a boat to their new home in a zoo. Put them on a cart, then use monkeys to push or pull them up a hill. Use the minimum amount of force needed to move each animal. For example, use a single monkey to push a pelican or use three monkeys to pull a zebra. This learning object is a combination of three objects ...

### Differential calculus: linear graphs

Observe the linear distance–time graph of a rocket travelling at a constant velocity. Calculate the average and instantaneous velocity of the rocket over different time intervals. Notice how as each time interval becomes smaller the rocket's average velocity is equivalent to its instantaneous velocity. Work out how the ...

### Differential calculus: non-linear graphs

Observe the non-linear distance–time graph of a rocket travelling at a changing velocity. Calculate the average and instantaneous velocity of the rocket over different time intervals. Notice how as each time interval becomes smaller, the rocket's average velocity approaches its instantaneous velocity. Use the slider to ...

### Differential calculus: the derivative

Observe the non-linear distance–time graph of a rocket travelling at a changing velocity. The distance, s, travelled by the rocket after t seconds is determined by the formula s(t) = t². Calculate the average velocity of the rocket over time intervals that become progressively shorter. Tabulate the results and look for ...
