# HTML5 PHYSICS SIMULATIONS

With Java applets on the decline for many years. JavaScript, HTML5, and other scripting languages have managed to take over applets both in terms of browser support and extra functionality. At EDinformatics we are transitioning from Java, Shockwave and Flash to HTML5 Simulations which can easily be used on all platforms.

### SELECTED PHYSICS HTML5 SIMULATIONS

Constant Velocity vs, Constant Acceleration

Graph constant velocity vs. constant acceleration. Ability to change velocity and acceleration of each object.

Projectile Motion

Ability to set launch speed and launch angle.

Comparison of a ball dropped and one launched horizontally-

Twop balls are set in motion under gravity. One is allowed to fall directly to the ground, the other is launched horizontally. Which ball hits the ground first.

Lever Principle

This app shows a symmetrical lever with some mass pieces each of which has a weight of 1.0 N. The lever arms can be read from the coloured rectangles; one rectangle corresponds to 0.10 m. The lever is in balance when the app is started. You can attach a new mass piece or put it to another place with pressed mouse button. In a similar way you can remove a mass piece by clicking on it.

Ball Rolling down a Ramp

Ability to change the height of ramp or base of the ramp.

Ball on a Spring

Horizontal Motion -- Position vs time.. ability to set the mass and spring constant.

Spring Scale Simulation (Phet)

Hang masses from springs and discover how they stretch and oscillate. Compare two mass-spring systems, and experiment with spring constant. Transport the lab to different planets, slow down time, and observe the velocity and acceleration throughout the oscillation. Go directly to simulation,.

Force and Motion

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Distance Between Atoms

Explore the interactions between various combinations of two atoms. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction.Go directly to simulation.

#### Ohms Law

See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law.

### HTML5 Physics Simulations for K-12 and Higher Education

#### PhET-

Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
