Find the relation between linear displacement and angular displacement
Answers
Linear displacement is movement in one direction along a single axis. A position or linear displacement sensor is a device whose output signal represents the distance an object has traveled from a reference point. A displacement measurement also indicates the direction of motion
Angular displacement of a body is the angle in radians (degrees, revolutions) through which a point revolves around a centre or line has been rotated in a specified sense about a specified axis. ... Thus the rotation of a rigid body over a fixed axis is referred to as rotational motion.
Answer:
The difference of position vectors of a particle at two different times is called linear displacement in that time interval. If d(theta) is infinitesimally small angular displacement, r is radius vector of the particle , then linear displacement, ds=r d(theta).
