Work power and energy

Work power and energy Work Work is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is constant, work may be computed by multiplying the length of the path … Read more

Force and laws of motion

Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more

Gravitational Force

The following are subtopics of Gravitational Force: Gravitational acceleration Gravitational constant Gravitational field Gravitational potential energy Gravitational waves Newton’s law of universal gravitation Tidal force Weight Gravitational force is the force of attraction between two objects with mass. The more mass an object has, the stronger its gravitational pull. The distance between two objects also … Read more

General Defences

   General Defences Vis Major or Act of God When something occurs over which you have no control and it is effected of accentuated by the forces of nature then you are not liable in tort law for such inadvertent damage that may arise out of such. However if you were well aware … Read more

Gravitational Force

Here is a list of subtopics without any description for Gravitational Force: Gravitational acceleration Gravitational constant Gravitational field Gravitational potential energy Gravitational waves Newton’s law of universal gravitation Tidal force Gravitational force is one of the four fundamental forces of nature, along with electromagnetism, the strong force, and the weak force. It is the force … Read more

work energy and power

Work energy and power Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force.Mathematically, work is the force-displacement product (for those of you who prefer algebra) W = F x s cos a or the force-displacement path integral (for those … Read more

electro magnetic induction, electric motor

Electro Magnetic Induction When a DC current passes through a long straight conductor a magnetising force, H and a static Magnetic Field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar … Read more
