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.

The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb. Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.

If you were performing this experiment in an in-class laboratory, you would be given one or more small iron balls. These would be utilized with a variant of the Free-Fall apparatus shown in the graphic below. (INSERT PICTURE HERE) You would first raise the upper black clamp to the desired height above the middle clamp. Then you would place the ball firmly in the upper clamp. Next, you would turn on the timer and adjust its initial reading to zero. After you release the ball, it falls towards the middle clamp. When it encounters this clamp, the timer stops and you can read the time of fall. Results are usually within 10% of the standard value of g. Here, in this online version, I will supply values of height (h) and time (t). First, calculate the average time (tav) for each height and use it as described next. You will use the third equation above to calculate the value of gravitational acceleration (g) in each case. Then, you will determine the…
