Steer a charged particle to a target, and observe forces and fields.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Generate all polar, all nonpolar, or random proteins and observe how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins...

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

In this interactive, drag a pendulum to set its initial height and observe how height is related to potential energy. Then release the pendulum and observe the change from potential energy to kinetic energy, and ultimately to thermal...
