Question

To describe circular motion with the help of thread and stone experiment on it​

Answer 1

Answer:

ommon sense suggests that any object in circular motion strives constantly to recede from the centre. This observation troubled great thinkers like Descartes and Newton. It took Newton some 20 years to incorporate circular motion into his thinking about forces and motion, as published in Principia Mathematica.

In this collection, the idea of a centripetal force is consistently used. We begin with qualitative experiments that focus students’ attention on the direction of the force causing a circular motion; later experiments are quantitative. Acceleration, a, needs a force, F, in the same direction, generally expressed as F = ma. Acceleration in a circle, v2/R, is centripetal, and so the force required to cause it is also centripetal.
