Energy is the ability of a body to do work.. In Physics, work has a precise and definite meaning. Electricity is sold in kilowatt-hours because that equals the amount of electrical energy consumed. The force we exert to lift the rock is equal to its weight, w, which is equal to its mass, m, multiplied by acceleration due to gravity, g. The work we do on the rock equals the force we exert multiplied by the distance, d, that we lift the rock. ) on the TV, because they have moved the same mass over the same vertical distance, which requires the same amount of upward force. Explain why you are not injured by such a spark. Supply: nofisunthi.blogspot.com A person holding a heavyweight at rest in the air may be working hard in the physiological sense, but from the point of view of physics, that person is not doing any work on the weight.

(b) Only a fraction of the workers lifted blocks; most were involved in support services such as building ramps (see Figure), bringing food and water, and hauling blocks to the site. Case 1: If the displacement is produced in the direction of the force i.e, = 0, then the work done will be: Thus, when a horizontal force moves a body horizontally or when a vertical force lifts a body vertically, then the work done is the product of force and distance covered by the object. 46. A weight lifter lifts a set of weights a vertical distance of 2.00 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights? Does the work you do on a book when you lift it onto a shelf depend on the path taken? (c) Discuss whether water resistance seems to increase linearly with velocity.
