SUMMARY
A pendulum swinging in a vertical circle cannot maintain a constant speed throughout its motion due to the conversion of kinetic energy (KE) to potential energy (PE) as it rises. As the pendulum ascends, its height increases, resulting in an increase in potential energy and a corresponding decrease in kinetic energy, which leads to a reduction in linear speed. The relationship between linear speed (v), angular velocity (ω), and radius (r) is defined by the equation v = ωr, indicating that if v decreases while r remains constant, angular velocity (ω) must also decrease.
