Work and Kinetic Energy 
This simulation is similar to the impulse/momentum simulation, but in this one the force is applied as the object moves through a specific distance, as opposed to the force being applied for a specific amount of time. When a constant force is applied over a particular distance, the momentum vs. position graph would be nonlinear, but the kinetic energy vs. position graph would be linear, so that's the graph we plot here. Just for fun, you can see the momentum vs. position graph, too, if you'd like to. 

Energy Bar Graphs 
This simulations shows the kinetic and potential energies of a swinging pendulum. 

Sliding Down a Ramp 
The object slides down the ramp. You can plot the total mechanical energy (purple), gravitational potential energy (red), kinetic energy (green), and the thermal energy (black) as a function of time or position. 

Sliding Down a Ramp (with Spring) 
The object slides down the ramp without friction, toward a spring at the bottom. You can plot the gravitational potential energy (red), the kinetic energy (green), and the elastic potential energy (blue) as a function of time or position. 

The Ramp 
Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work 

Energy Skate Park: Basics  Learn about conservation of energy with a skater gal! Explore different tracks and view the kinetic energy, potential energy and friction as she moves. Build your own tracks, ramps, and jumps for the skater.  
Energy Skate Park  Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!  
Coaster  Animation shows a car coasting on a curve. Losses of energy due to frictional forces have been ignored in modeling the behavior of the car. Besides energy conservation ideas, some dynamics of circular motion ideas also get highlighted. The car starts with negligible velocity from the initial position. The dots on the path should help to relate to changes in the velocity of the car as it moves along the path.  
Conservation of Energy  This fun applet lets you adjust the initial conditions of a skier to investigate conservation of energy.  
Energy Forms and Changes 
Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and changes through your system.
