Oscillation exercise (physics 2) In the image, a pendulum is composed by a disc with 5cm radius and 500g of mass fixed by a bar with length L = 1m and 500g of mass. I have to calculate (a) the momentum of inertia of the pendulum in relation to the point of rotation, which is located in the center of a disc with 3cm radius and 200g of mass and (b) the rotation frequency.
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.
