For each of the following statements determine whether it is true, false or undetermined. False False False True False Submit Answer Your apparent weight is less than mg when moving in an elevator that is moving downward. Water is removed from clothes in a spin dryer by centrifugal force that throws the water outward. In order for an object to travel in a circle, a force must be applied on the object that points away from center of the circle. The magnitude of the gravitation force exerted by the Earth on the Moon is same as the Moon exerts on the Earth.

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.
