Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929) Under these

They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries‚ and can be summarized as follows: 1- The first law states that an object continues in its state of rest or uniform motion in a straight line unless compelled
