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.
A wine barrel has a radius of 30.0 cm.
1A. If the edge of the barrel moves 210 cm, through what angle does the tire rotate?
Note that s = rθ where s is the arc length and r is the radius
s/r is in radians, π rad = 180 deg
1.B If the barrel rotates through an angle of 0.35 radians, how far does a point on the
edge of the barrel rotate?
1.C If a point 22 cm out from the center rotates along an arc length of 65 cm, through
what angle does the barrel rotate?
