A wheel with rotational inertia 47 kg.m2 is mounted on a fixed, frictionless axle. The angular speed of the wheel is increased from zero to 46 rad/s in 10-s. What is the average net torque/Moment in N.m on the wheel during this time interval?
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
