    Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

    1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow
