Circular Motion and Gravitation Circular motion is everywhere‚ from atoms to galaxies‚ from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general‚ we say that an object rotates when the axis of rotation lies within the body‚ and that it revolves when the axis is outside it. Thus‚ the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis‚ all the particles of the body revolve – that is‚ they move in circular paths about

Introduction Global warming is the term used to describe a gradual increase in the average temperature of the Earth ’s atmosphere and its oceans‚ a change that is believed to be permanently changing the Earth’s climate. Some people do not believe that these are caused by human activities. They think it is all political and falsehood intended to cause panic among humans‚ some call it a hoax. (Dauncy & Patrick‚ 2001). But climate scientists looking at the data and facts agree the planet is

Uniform Circular Motion – a constant motion along a circle; the unfirom motion of a body along a circle Frequency (f) – the number of cycles or revolutions completed by the same object in a given time; may be expressed as per second‚ per minute‚ per hour‚ per year‚ etc.; standard unit is revolutions per second (rev/s) Period (T) – the time it takes for an object to make one complete revolution; may be expressed in seconds‚ minutes‚ hours‚ years‚ etc.; standard unit is seconds per revolution
