Conceptual Questions on Rotatory and Circular Motion
This page consists of solved conceptual questions on Rotatory and Circular Motion included in the course of Physics for Grade 11.Q 1 | Why is the fly wheel of an engine made heavy in the rim? See Answer |
Q 2 | Why is a rifle barrel ‘rifled’?
See Answer |
Q 3 | Is it possible for a person to distinguish between a raw egg and a hard boiled one by spinning each on a table? Explain. See Answer |
Q 4 | Why is the acceleration of a body moving in a circle, directed towards the center?
See Answer |
Q 5 | A ball is just supported by a string without breaking. If it is set in swinging, it breaks. Why?
See Answer |
Q 6 | An insect is sitting close to the axis of a wheel. If the friction between the insect and the wheel is very small, describe the motion of the insect when the wheel starts rotating.
See Answer |
Q 7 | Explain how many minimum number of geo-stationary satellites are required for global coverage of T.V transmission?
See Answer |
Q 8 | Explain the significance of moment of inertia in rotatory motion.
See Answer |
Q 9 | Why does the coasting rotating system slow down as water drops into the beaker?
See Answer |
Q 10 | A body will be weightless when the elevator falls down just like a free falling body. Explain.
See Answer |
Q 11 | When a tractor moves with uniform velocity, its heavier wheel rotates slowly than its lighter wheel, why? Explain.
