Derive expression for potential energy stored by stretched string |
| Answer» The extension produced x is directly proportional to the force applied to extend or compress the spring. F=kx were k is spring constant. The work done to stretch or compress the spring is stored as its PE W= integral 0 to x (Fdx) =0 to x (kxdx) =1/2 kx^2 | |

Difference between centre of mass and centre of gravity |
| Answer» Centre of mass is the point at which the distribution of mass is equal in all directions and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions and it does depend on gravitational field. The centre of mass and centre of gravity are in same position if the gravitational field in which the object exists stays uniform. | |

What is cofficient of friction |
| Answer» A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object\'s normal force or frictional force when other methods aren\'t available. | |

Difference between kinetic energy and potential energy |
|
Answer» The energy which possess by a body due to its motion is known as kinetic energy and the energy which possess by a body due to its rest is known as potential energy. Kinitic energy is the energy that occur in a body by the motion of the body.Potential energy is the energy that is present in a body by the virtu of it\'s position |
