describe an activity to measure the time period of simple pendulum
Answers
Suspend a metallic ball (bob) by a long thread from a rigid support. Your simple pendulum is ready. Set the simple pendulum in motion. Note the time in your watch when bob is at an extreme position (say A).
Answer:A point mass attached to a light inextensible string and suspended from fixed support is called a simple pendulum. The vertical line passing through the fixed support is the mean position of a simple pendulum.
The vertical distance between the point of suspension and the centre of mass of the suspended body (when it is in mean position) is called the length of the simple pendulum denoted by L
Explanation:A point mass M suspended from the end of a light inextensible string whose upper end is fixed to a rigid support. The mass displaced from its mean position.
Assumptions:
There is negligible friction from the air and the system
The arm of the pendulum does not bend or compress and is massless
The pendulum swings in a perfect plane
