Have fun with Science Animations full of math and physics for primary and secondary schools. Math and physics concepts covered are: numbers, coordinates, area, volume, speed, velocity, acceleration, torque, stress, pressure, momentum, Pythagorean theorem, energy, telling time, ratio, rate, frequency, algebra, gravitation, force, electricity, Bernoulli, shapes, differentiation, circle geometry, gears, engine, orthographic projections, pneumatic simulator, waves, exponents and perspective.
Play and learn with toy cars, a slinky, Newton's cradle, building blocks, 3D shapes, planets and even launch a satellite!
These animations are powerful educational media; they make understanding of dynamic and 3D concepts much easier. Math and Physics animations don't replace handbooks; they support handbooks because they can do things that handbooks can't do. There is no age restriction - the younger, the better. Math and Physics animations put fun into learning.

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. The categories are:. In addition, I have prepared a small tutorial in using Flash to do Physics animations.
It contains screen shots and embedded Flash animations, so the file size is a k. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. There are 99 animations listed below. Some are simple; others are more complex. The most recent animations added to the list are identified.
Two balls falling near the Earth's surface under the influence of gravity. The initial horizontal speed of one of the balls may be varied. Requires Flash 6; file size is 11k. Many animations have been translated into Greek by Vangelis Koltsakis. Many animations have been translated into Polish by the edukator. This "master index" page to my animations turns out to be linked to from a number of other sites.
This surprises and delights me. A few of those sites are:. Educational Technology blog from the Univ. These animations were written by David M. Harrison, Dept.

The decay of atoms of the fictional element Balonium.Continuing in the series on Physics in Animation, today we take a closer look at Force and Momentum. How can these principals help you to take your work to the next level? As discussed in Parts 1 and 2, the Principles of Animation Physics are helpful for animators looking to create physically believable motion.
These principles are:. To understand how forces, such as gravity, friction, etc. Moving objects have momentum, which depends on both their speed and weight. A character that weighs pounds 45 kilos can have as much momentum as a pound character if the small character runs three times faster than the big guy.
Momentum also depends on the direction of the motion so deflecting a moving object is considered a change of momentum. The Law of Inertia Principle 2 tells us that we have uniform motion constant timing and spacing Spacing is the distance an element travels between two frames of an animation. By increasing and decreasing the spacings So, as an animator, how do you use this principle? The punch which is our unbalanced force should cause a quick change in momentum.
For example, you can have the character accelerating quickly as he recoils from the punch. Or if the character was already moving when the punch landed then the force could quickly stop his motion.
In both cases we have a change in momentum and the larger the force, the quicker this change occurs. Remember that momentum depends on both velocity and weight so a heavy character recoils less than a light character hit by the same punch.
This is a great way to convey a sense of weight for characters by showing how they react to forces. When this friction is small the momentum changes slowly which means it takes a long time for the character to come to a stop.
The principle of Force and Momentum also tells us that if the force is constant which is typical for sliding friction then the change in momentum produces spacings that follow the Odd Rule see the principle of Timing, Spacing, and Scale in Part 1. Often the unbalanced force is not constant.
If the unbalanced force is increasing then the spacings change faster than the Odd Rule. On the other hand, if the unbalanced force is decreasing then the spacings become more uniform. For example, when Tarzan is swinging from tree to tree his speed is nearly constant near the bottom of the arc. In that part of the swing the downward force of gravity is almost balanced by the upward tension in the vine. Shoot some reference and see for yourself! Besides timing and spacing Spacing is the distance an element travels between two frames of an animation.
Moreforces also affect the path of action; as mentioned above a change in direction is considered a change in momentum. So if you have a pair of characters running towards each other and colliding such as in a football matchthe greater the deflection of their motion, the greater the force of impact.
While watching motion, try to think in terms of how momentum is changing and the forces causing this change. Both the timing and the path of action depend on these unbalanced forces so your animated motion will be believable only if the texture of the timing and the shape of the path of action are consistent with the forces at play. In brief: Use the force!
