pacific ocean plate tectonic evolution
Return to Animations Evolution of the Pacific Ocean (150 mya - Present) The Pacific Ocean is the world's largest ocean, covering nearly one-half of the globe. Though huge, the Pacific is getting smaller. It was once much wider when all the continents were joined together in the supercontinent, Pangea. The Pacific ocean basin is getting smaller because the Atlantic Ocean is opening and North America and South America are moving westward.
We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing.
Physics Flash Animations
Ripple tank: circular wave reflection Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrating circular wave reflection in a ripple tank. Click in the water to generate a circular wave that undergoes reflection at the tank boundary. This resource is from the unit Bouncing Waves which is part of Absorb Physics . The full Absorb Physics course normally sells for £400 - but you can get it free for your school!

The electromagnetic spectrum
The electromagnetic spectrum Added by David Fairhurst on Feb 6, 2008 An interactive animation showing the electromagnetic spectrum. Place the cursor over the different parts of the spectrum to find out what they are, how the waves are generated, what materials they pass through and what they are absorbed by.IR camera Added by David Fairhurst on Feb 6, 2008 An interactive animation showing a night-time view of a town. Click on the animation to view the scene using an infra-red camera. Ask pupils to identify what they can see.

Real waves on water
Real waves on water Added by David Fairhurst on Feb 6, 2008 An interactive animation illustrating how real water waves propagate. The motion of water molecules on the surface of the water is highlighted to demonstrate that they move in circles.
Diverging lens Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrating the virtual image of a pencil produced by a diverging lens. Move the object pencil left and right to observe the image produced.
Diverging lens
Converging lens Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrating the real and virtual images of a pencil produced by a converging lens. Move the object pencil left and right to observe the image produced. This resource is from the unit Converging Lenses which is part of Absorb Physics . The full Absorb Physics course normally sells for £400 - but you can get it free for your school!

Combining waves 2 destructive interference
Combining waves 2: destructive interference Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrating destructive interference. Three strings of beads are shown: one travelling right to left; the second travelling left to right and the third is the superposition of the first two. Use the slider to propagate a wave or use the step button to slow down the animation. This resource is from the unit Interference which is part of Absorb Physics .
Combining waves 1 constructive interference
Combining waves 1: constructive interference Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrating constructive interference. Three strings of beads are shown: one travelling right to left; the second travelling left to right and the third is the superposition of the first two. Use the slider to propagate a wave or use the step button to slow down the animation.A wave: squeezing a spring Added by David Fairhurst on Feb 6, 2008 An interactive animation illustrating a longitudinal wave. Click the arrow button to play the animation.

Investigating weight and upthrust
Investigating weight and upthrust Added by David Fairhurst on Feb 6, 2008 An interactive animation illustrating upthrust with a rock and an apple. Click the arrow button to lower an object into the water and raise it again. A spring balance displays the apparent weight of the object in and out of the water. Click the arrow button to change the object.Balancing a seesaw Added by David Fairhurst on Feb 6, 2008 An interactive animation demonstrates a seesaw. Two weights on the seesaw and moved backwards and forward and their weight adjusted to balance or unbalance the seesaw.
