GENERAL KNOWLEDGE

Detailed explanation-1: -Explanation: The time taken for the object to complete one revolution around the circle is referred to as the time period and is commonly denoted by the symbol . Thus, the average speed of an object in circular motion is given by the expression 2 R T .

Detailed explanation-2: -The period of circular motion is equal to the circumference of the circle (2r 2 r ) divided by the object’s speed (v ).

Detailed explanation-3: -The period of the object’s motion is defined as the time for the object to complete one full cycle. Being a time, the period is measured in units such as seconds, milliseconds, days or even years. The standard metric unit for period is the second.

Detailed explanation-4: -Since the formula for velocity (speed actually, since we are looking for the magnitude of velocity) is given by distance divided by time, we can simply find the circumference and divide it by the period to get the magnitude of velocity of the object.

Detailed explanation-5: -For a mass M with tangential speed v at radius R, the centripetal force is Fc = Mv2/R. With a period of T, the linear speed is v = 2R/T and the centripetal force is Fc = 42MR/T2. You will change Fc, mass, and radius to measure the effect on the period of rotation.
