6. When an electric motor is turned on at t = 0, its angular acceleration is ? = 10e-0.5t where t is the time in seconds. What is the terminal angular velocity of the motor in rpm? 7. Referring to problem 6, how many revolutions are required for the motor to reach half of its terminal angular velocity.
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.
