Study Notes
Simple Pendulum
- A simple pendulum is a massless string with a point mass attached to its end, which oscillates about a fixed point.
Factors Affecting the Period of a Simple Pendulum
- The period of a simple pendulum is not affected by the mass of the pendulum.
- The period of a simple pendulum is not affected by the amplitude of the oscillation.
Relationship Between Period and Length of a Simple Pendulum
- The period of a simple pendulum is directly proportional to the square root of the length of the pendulum.
- The period of a simple pendulum can be calculated using the formula: T = 2π √(l/g), where T is the period, l is the length of the pendulum, and g is the acceleration due to gravity.
