Balancing stick - rotational Inertia
"Sorry, for coming late " said the kid who was panting . When I asked him "What happened, that got you delayed?". He said "I was running back from the shop and couldn't stop myself from running even after coming closer home". " Wonderful! you just experienced something called inertia in physics, dear" I replied. And that's how the class started this week. What is Inertia?. Inertia is the tendency of a body to resist any change in motion or at rest. This can be explained with a simple example. When a vehicle stops, you tend to jerk forward before coming to a stop. Also, when a vehicle starts you tend to jerk backward. What is rotational Inertia? Rotational inertia measures how much an object resists the change in rotation. Rotational inertia depends on the distribution of the mass in the stick. For example, when a sportsman is holding a bat (baseball) and swings it, he can swing quickly if he chokes the bat by reducing th
