In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the direction of the force and..

A dancing or running man is said to be more energetic than a sleeping man. In physics, a moving particle is said to have a more energy than an identical particle at rest. Quantitatively, the energy of the moving particle is given by The kinetic energy of a sy..

Machine - From times immemorial, man has used machines to help him in his work. Today, we are dependent on machine for almost every task. When we think of machines we always tend to think of big and complicated units with many moving parts like wheels and rollers and gears and shafts. In ..

. An unbalanced force changes the state of constant velocity including zero velocity of a body on which it acts. Forces may be balanced or unbalanced. An iron ball suspended from a hook by a wire [Figure (a) shown below] has two forces acting on it, its weigh..

Energy - Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign thes..

Summary - Machine is a device that is used to multiply force, or to gain speed, or to change the direction of a force, or transform energy. Levers, pulleys, inclined plane and gears are some of the examples of simple machine..

The force that acts during m otion between the two bodies in contact is called the kinetic frictional force. Once the block is in motion and the value of the applied force is just equal to the value of kinetic friction, the block neither accelerates..

Consider a body of mass 'm' which is initially at rest. When a force 'F' is applied on the body, let it start moving with a velocity 'V' and cover a distance 's'. The force produces acceleration 'a' in the body. The force 'F' does work when it moves the body ..

Tutors are very patient to explain me the same problem again and again until i understand...Really helpful...Thank you all...
I am Jessica from New York, I got excellent English tutors from Tutor Vista, who helped me lot to overcome my grammar mistakes, Thanks a lot...
I got almost 4 hours continues help for my test last night, you guys are awesome and very patient. Thank you
For every concept, here we get explanation along diagrams, I really liked it very much
