Answer 2

The period of revolution of a particle performing UCM  

Explanation:

• The period is the time required for the object to complete one revolution of motion.
• The angular speed is the angular displacement per second and it is related to the frequency by: ω=2πf with ω in rad/s.

• In circular motion time taken by object to complete one revolution on its circular path is called its time period.SI units is sec.
• When an object moves in a circular path with constant speed then the motion is called uniform circular motion.

• The period - the time taken by the object to complete one revolution.
• Frequency - The total number of revolution in one second is called the frequency.

• There exists an important relationship between angular velocity and frequency and it is given by the following formula: angular velocity is equal to the product of the frequency and the constant 2pl.

• The constant 2pi comes from the fact that one revolution per second is equivalent to 2pi radians per second.
