Final answer:
The period of circular motion is the time for a point to complete one revolution, calculated by dividing the circumference of the circle by velocity. For pendulums, it is determined by the formula involving the length of the pendulum and acceleration due to gravity.
Step-by-step explanation:
To determine the period of the circular motion of a point, we must consider the time it takes for the point to complete one full revolution around the circle. The formula to calculate the period is T = (Circumference of the Circle) / (Velocity around the Circle). Assuming the circumstances involve constant speed and a known radius or circumference and velocity, this equation can be applied directly. However, without specific values given for the circumference of the circle (2πr) or the velocity (Umax), we cannot calculate an exact period for the circular motion. In the context of a pendulum, the period can be calculated using the length of the pendulum and the acceleration due to gravity with the formula T = 2π√(L/g).
