The differences between the mass of an object and its weight is tabulated below.
|Mass is the quantity of matter contained in the body.||Weight is the force of gravity acting on the body.|
|Weight is the force of gravity acting on the body.||Weight is the force of gravity acting on the body.|
|It only has magnitude.||It has magnitude as well as direction.|
|Mass is a constant quantity.||Weight is not a constant quantity. It is different at different places.|
|Its SI unit is kilogram (kg).||Its SI unit is the same as the SI unit of force, i.e., Newton (N).|

Illustrate the law of conservation of energy by discussing the energy changes
which occur when we draw a pendulum bob to one side and allow it to oscillate. Why
does the bob eventually come to rest? What happens to its energy eventually? Is it a
violation of the law of conservation of energy?
