WebSolution. Force is a type of influence that can alter the state of rest or motion of a body. When a force applied to a body produces displacement, work is said to be done by the force. If there is no displacement, no work is done. Work done, W = F · s (where F is the force applied and s is the displacement. Energy is the capacity of a body to ... Web(a) Explain (i) work: (ii) power (b) Show that the efficiency E, the force ratio M.A. and the velocity ratio V.R. of a machine are related by the equation: E = M.A. x 100% V.R. (c) An inclined plane of angle 15° is used raise a load of 4500N through a height of 2m. If the plane is 75% efficient calculate: (i) velocity ratio of the plane;
How are force and work related? - eNotes.com
WebWhereas work is described as force acting through a distance, torque is described as force acting along a distance. Torque is something that creates twisting and tries to make something rotate. If we push on an object with a force of 10 lb and it moves 10 inches in a straight line, we have done 100 in-lb of work. WebIn physics, the term work has a very specific definition. Work is application of force, f, to move an object over a distance, d, in the direction that the force is applied. Work, … chronicles of narnia parody

WebA force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy. is the capacity for doing work. You must have energy to accomplish work ... which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts. Index Work concepts ... WebA girl pushes a load of mass 20kg to a distance of 10 metres in 5 seconds calculate (1) the work done (2) the energy used (3) the girl's power (a=g=10m/s square) i need help … WebWork, Energy, & Power - Chapter Summary and Learning Objectives. This chapter's instructors provide you with real-life examples of the forces at play when energy is expended to move an object. dereham taylor wimpey
