Energy

Kinetic energy of a bicycle

As the person starts pedaling, the speed and kinetic energy increase, do they increase at the same rate?

Kinetic energy, mass and speed

Try to give the same amount of energy to the three vehicles and observe their speeds. Which vehicle moves with more speed for identical energy?

Energy in a pendulum

When the pendulum is released, it begins to swing back and forth. At what point are the kinetic energy of the ball maximum and minimum?

Energy in a spring

Energy on an astronaut

Energy skate park

Learn about energy conservation with a skateboarder! Build tracks, ramps and jumps for the skater and see the kinetic energy, potential energy and friction as he moves. Measure speed and adjust for friction, gravity and mass - you can also put the skater on different planets or in space!
