A ball of mass m is attached to a string and swung around in uniform circular motion with radius R and speed v. A toy car of the same mass moves in uniform circular motion with radius R and speed v. The forces required to keep the bal and the car in uniform circular motion are: (choose the answewer). 1-No answer text provided. 2-the same for the ball and the car 3-higher for the car, because of friction with the road 4-not covered in this reading assignment
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.
