Find the power delivered to the truck. [given: 1000 kg as the mass of the truck] first we need to calculate the work done, which requires the force necessary to lift the truck against gravity: f = mg = 1000 x 9.81 = 9810 n. w = fd = 9810n x 2m = 19620 nm = 19620 j. the power is p = w t = 19620j 15s = 1308 j s = 1308 w.

Introduction to work, energy, and energy resources; 7.1 work: the scientific definition; 7.2 kinetic energy and the work energy theorem; 7.3 gravitational potential energy; 7.4 conservative forces and potential energy; 7.5 nonconservative forces; 7.6 conservation of energy; 7.7 power; 7.8 work, energy, and power in humans; 7.9 world energy use. Lesson 1 basic terminology and concepts. definition and mathematics of work. calculating the amount of work done by forces. potential energy. kinetic energy. mechanical energy. power. lesson 2 the work energy relationship. internal vs. external forces. The joule (j) is the metric unit of measurement for both work and energy. the measurement of work and energy with the same unit reinforces the idea that work and energy are related and can be converted into one another. 1.0 j = 1.0 n∙m, the units of force multiplied by distance. 1.0 n = 1.0 kg∙m s 2, so 1.0 j = 1.0 kg∙m 2 s 2.

Basic introduction into work, energy, and power. forms of energy such as kinetic and potential energy. it discusses the work energy principle, the relationsh. For this problem, we need to use the definition of power = force x velocity cos ø, where the angle ø in this problem is between the force and velocity, and is 90° – 28° or 62°. therefore: power (p) = f • v cos ø where f = weight of 120 kg. 2000 w = (120 kg) (9.8 m s2) (v) cos 62°. v = 2000 w ÷ 552 j.
