Question

can someone please explain formula of pendulum of class 7
​

Answer 1

mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.

Answer 2

Answer:

The time taken by pendulum bob to make one complete oscillation is called time period of the pendulum. The time taken by bob to travel from position B to C and back to B is the time-period of pendulum. The time taken by bob in going from position A to B, then from B to C and back to A is also equal to time-period
