On the diagram above extend each force of gravity vector so that it reaches the floor. The "pivot" will be the toes. The perpendicular distance will be the distance along the floor between the toes and the extended force of gravity. Label these distances on the diagram. Using these labels, explain why the person on the left rotates clockwise while the person on the right experiences no rotation (you may have to adjust your center of mass position).
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.
Using these labels, explain why the person on the left rotates clockwise while the person on the right experiences no rotation (you may have to adjust your center of mass position). _____________________________________________________________________
