View how the curve and the data are responding to the changes of the cable length, the distance between its two ends and the weight per unit length.

View how the coupled harmonic oscillation of the two carts are responding to the changes of the Hook constants of the springs, their initial positions and the frictional constant.

View both the spinning and circular motions of the Earth and understand how they bring days, nights and the four seasons to our Earth.

Thin Lens and The Thin Lens Equation

View the image of an object is responding to the changes of its distance to the lens, its height and the type of lens (converging or diverging).

Spherical Mirror: Concave, Plane and Convex

View the image of an object is responding to the changes of its distance to the Mirror, its height and the type of Mirrors (Concave, Plane and Convex).

• Diesel Engine and Diesel Cycle

• Otto Engine and Otto Cycle

  View the four strokes of engines and the correspoding curves on the PV diagram.
