Answer:
I have one....the maths tricks by showing the real diagram
Answer:
Step-by-step explanation:
Take a cricket ball (Or a stone). Wrap some cloth around it.
Take some cord/thread (measure the length of the cord say, 1m)
Hang the cord at the ceiling.
Tie the ball with cloth at the end of the cord.
Congratulations you've made a simple pendulum!
Push it with a little force(not very high) and it'll oscillate.
Measure the period of oscillation by any smartphone with stopwatch.
Take average value of period from 5 (or 10) oscillations to minimize any error.
Prove the math#1:
Where,
T = Time period measured (in sec);
l = Length of your pendulum (in m);
g = 9.8 m/sec2 (gravitational time constant).
See the math#2: Observe the shadow of the ball on the floor while it oscillates. This exactly follows a sinusoidal wave in real life!
