Linear and angular motion

Publisher Summary

This chapter focuses on linear and angular motion. The unit of angular displacement is the radian, where one radian is the angle subtended at the center of a circle by an arc equal in length to the radius, The speed of revolution of a wheel or a shaft is usually measured in revolutions per minute or revolutions per second but these units do not form a part of a coherent system of units. The basis used in SI units is the angle turned through in one second. Angular velocity is defined as the rate of change of angulardisplacement, θ, in regard to time, t and for an object rotating about a fixed axis at a constant speed. Linear acceleration is defined as the rate of change of linear velocity in regard ...
