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.

VII. Find the magnitude D + E and D- E where vector D = 31 - 4j - 2k and vector E =
41 - j - 2k.
VII the force vector F, has a magnitude of 30.0 N pointing in the - z-direction and force
vector F, has a magnitude of 60.0 N pointing at the + x-direction, find its dot product and
its cross product. How would the answer change if the vectors switched positions
(commutates) in the equations?
