Working Of A DC Motor

Objective here is to show the workings of a DC motor, and explain what makes a coil to rotate, as well as change its speed. Fleming’s Left Hand is used to explain the direction of motion of the coil, in conjunction with force acting upon the coil. A user is allowed to “play with” the DC motor parts and understand the impact of changes they make to those parts.

Vector Additions

Ever wondered what happens when 2 forces act on a body at the same time. How do these forces add up to produce a resultant force ? Lets make it a little interesting here. Lets go on a boat trip to find this out. Lets see you control a speed boat against a river current. If you cross this challenge, we have a tougher one for you – try manoeuvring 2 boats to tug a raft. Put your game faces on and lets get down to some serious business here.

Flow Of Electrons In A DC Circuit

Objective here is to help a user explain (or understand) the difference between conventional direction of current versus direction of flow of electrons in a conductor. Students also get to understand why the brightness of a bulb changes when we change an external resistor in the circuit. Interactive aspects include ability to change the conductor, and resistors to see impact of those changes in the circuit.

Centripetal Force

Objective here is to help understand forces acting on an object traveling in a circular motion. A common real life example is taken to depict this scenario. A person standing on a merry-go-round without any support, tries to balance himself in the ride. A curious mind will wonder what causes such a person to slip and fall away from the ride !!
