Interactive simulation of how populations change under different environmental pressures. Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients.

Online simulation: Kinetic theory and States of matter (Phet/UC Boulder)

Interactive simulation of how the microscopic picture of matter relates to measurements like temperature, pressure, and energy flow. Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Interactive game to hit a target with a projectile by setting the initial speed and angle. Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.

Online Game: Dynamics of Landing on a planet (PhET/UC Boulder)

Interactive game: Manipulate thrust, get acceleration and velocity just right to avoid a crash. Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Online simulation: Ramp motion and Free body diagrams, Velocity and Acceleration graphs (PhET/UC Boulder)

Interactive simulation of simple 1-D motion under gravity, normal, friction, and an applied force. Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces)
