explain free body rotation with an example
Answers
In Newtonian physics, the latter term refers to a body which is falling under pure gravity with all other forces being zero. In Einstein's general theory of relativity, where gravity becomes curvature of spacetime, a freely falling body is subject to no forces whatsoever and is a body moving along a geodesic.
Rotational motion Examples
Rotational motion ExamplesMotion of wheel, gears, motors, etc is rotational motion. Motion of the blades of the helicopter is also rotatory motion. A door, swiveling on its hinges as you open or close it. A spinning top, motion of a Ferris Wheal in an amusement park.
A free body diagram consists of a diagrammatic representation of a single body or a subsystem of bodies isolated from its surroundings showing all the forces acting on it. A series of free bodies and other diagrams may be necessary to solve complex problems.
