Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

Introduction Mathematics is an indispensable subject of study. It plays an important role in forming the basis of all other sciences which deal with the material substance of space and time. What is Mathematics? Mathematics may be described as the fundamental science. It may be broadly described as the science of space‚ time and number. The universe exists in space and time‚ and is constituted of units of matter. To calculate the extension or composition of matter in space and time and to

1840’s. There is no evidence of it taking place in America. The scientific realm was still dominated by Newtonian thinking‚ even though Sir Isaac Newton issued his dynamic compositions in the mid-1600s. Newton enlightened everyone on the fields of physics and mathematics so that the world can figure nature out by the use of proper scientific methods. This Newtonian Era
