Mechanical energy Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Introduction: We use a system consisting of two weights hanging at each end of a thin thread lying over a wheel. A photo gate is placed so that the light is interrupted by the spokes of the wheel. The data are recorded electronically and this makes it possible... ### Potential Energy

﻿Tutorial – Work, Energy (Assume the acceleration due to gravity, g = 9.81 m/s2 ) 1. Calculate the work done when a force of 40 N pushes an object a distance of 500 m in the same direction as the force. 2. Calculate the work done when a mass is lifted vertically by a crane to a height of 5 m, the force required to lift the mass being 98 N. 3. A spring, initially in a relaxed state, is extended by 100 mm. Determine the work done by using a work diagram if the spring requires...

Expriment 4: Work, Power and Energy Department of Math and Physics College of Science, University of Santo Tomas Espana, Manila Philippines Abstract Two activities were performed in this experiment. For the first activity, the weights of the different members of the group were each computed and were used in order to determine how much work and power each member exerted in climbing up and down the stairs while being timed. From the data obtained, it is apparent that as one is faster...

only 1 of each 5 × 109 incident photons is absorbed and causes an electron to be ejected from the surface, the total photocurrent in the circuit is ________. 3. Light of wavelength 330 nm falling on a piece of metal ejects electrons with sufficient energy which requires voltage V0 to prevent a electron from reading collector. In the same setup, light of wavelength 220 nm, ejects electrons which require twice the voltage V0 to stop them in reaching a collector. Find the numerical value of voltage V0...

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming...

Holt Physics—Chapter 5: Work and Energy Price I. Section 5.1—Work A. Definition of work 1. Work does not mean the same thing in Physics as it does in the everyday sense of the word. 2. Work is defined as a force causing a displacement. Work = force x displacement W = Fd 3. Work is NOT done on an object unless the displacement is greater than zero 4. The only forces that are considered to do work are those that...
