User controls the dropping of a bomb from a World War 2
bomber. Bomber's horizontal velocity and the position of the target can be
varied before running the simulation. This simulation aims to help student grasp
the concept of independent vertical and horizontal motion of an object in a
projectile.

A problem on moment (turning effect of a force) is presented. Students have to find out the minimum force required to push a heavy wheel up a step by using the concept of moments. The students can also try out the different turning effect produced by the same force applied at different positions and directions on the wheel.

User controls when to stop a moving car by applying the
brake. Variables such as the original velocity of the car and the coefficient of
friction between the tyres and road can be varied. Students will find it easier
to understand how the stopping distance depends on these
factors.

A charged particle moving in a magnetic field User shoots a charged particle into a region of magnetic
field and observes how its motion is affected. Variables such as magnetic field
strength and direction, velocity (both magnitude and direction), quantity of
charge carried by the particle can be varied to help students see how they
affect the motion of the charged particle in the magnetic
field.

A trolley's motion is being
explored in this model. User can vary the size of the force acting on the
trolley. The mass of the trolley can be changed by stacking weights on it.
Students can investigate how these two factors (force and mass) affect the
motion of the trolley.

Projectile - object thrown upward It is a common misconception that when an object is
thrown vertically up from a moving train, the object will land behind the train.
In this simulation, students can explore this by throwing an object vertically
up from a moving trolley. They can see that how the object moves and where it
lands depend on the velocity of the trolley, the force with which they throw the
object and the amount of air resistance present.

Man in a lift
In this simulation model, the user can control the acceleration of a lift and observe what will happen to the man and its apparent weight when the acceleration is upward, zero, or downward. If the acceleration is set to be more than 9.8 ms^2 downward, the man will lose contact with the floor of the lift and he is free falling. |

Oscillation of a mass attached to a horizontal spring A mass attached to a horizontal spring can be set into oscillation by extending or stretching through a small displacement. Graphs of the mass's displacement, acceleration, kinetic energy and potential energy are displayed in real time. User can vary the force constant of the spring and damping factor to see how they affect the oscillation of the mass. |

This simulation model demonstrates forced oscillation and resonance. The user can adjust the frequency of a driving source which is driving a mass-spring system into oscillation, and then observe how the amplitude of the driven oscillator varies with the drive frequency. Resonance occurs when the drive frequency matches the natural frequency of the mass-spring system. The phase relationship between the driving and driven oscillators can also be seen in the displayed graphs. |
