Work done on the body by force or work done by the body ?

What is necessary for work done when the force is exerted on the body ?

A body displaced 10m under the force of 10 N . If the work done on the body is 50 J , then the angle between the force and displacement will be ……..

A body of mass 2 kg initially kg intially at rest moves under the action of an applied horizontal force of 7 N on a table with coefficient of kinetic friction = 0.1 Compute the (a) work done by the applied force in 10 s. (b) work done by friction in 10 s . work done by the net force on the body in 10 s. (d) Change in kinetic energy of the body in 10 s and interpret your details .

A body of mass 2 kg is rest on a smooth horizontal surface . When a horizontal force of 0.5 N acts on this bofy it is displaced in the direction of the force . Find the work done by the force in 8.0 s .Show that this work is equal to the change in kinetic energy of the body .

What will be the work done on the body moving with constant speed ?

What is the work done on the body moving in uniform circular motion ?

One body is displaced in the direction of X - axis up to 4 meter under influence of (-1,2,3) N force. Find work done by the force .

The work done by a force F_1 is larger than the work done by another force F_2 . Is it neccesary that power delivered by F_1 is also larger than that of F_2 ? Why

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body , express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also read from thte graph the work done when the distance travelled by the body is (1) 2 units (ii) 0 unit .
