This apparatus is consisting of two equal loads which are connected with a small mass thread. The thread is passed through with small mass pulley and almost friction free. At first this apparatus is used to learn the motion concept and to measure the earth gravitation acceleration "g". Physics experiment using Atwood machine, object motion relatively slow, load motion is accelerated are used to understand the Newton Law II about motion.

Time measurement can be done manually using a stopwatch or for better accuracy results, use Time Counter System which is consisting of Photo Gates and Timer Counter.

Provided with experiment manual book.

Some experiments need some other supporting tools or other components that can be borrowed from other kit.
