Concept explainers

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.

Question

Week 18 Unit 3 Practice: FRQ
1.
An experiment is performed using the apparatus above. A small disk of mass m, on a frictionless table is attached
to one end of a string. The string passes through a hole in the table and an attached narrow, vertical plastic tube.
An object of mass mz is hung at the other end of the string A student holding the tube makes the disk rotate in a
circle of constant radius r, while another student measures the period P.
(a) Derive the equation P = 27 that relates Pand m.
The procedure is repeated, and the period P is determined for four different values of mz, where m, - 0.012 kg and
r-0.80 m. The data, which are presented below, can be used to compute an experimental value for g.
m2(kg) 0.020 0.040 0.060 0.080
P(s)
1.40 1.05 0.80 0.75
(b) What quantities should be graphed to yield a straight line with a slope that could be used to determine g?
(c) On the grid below, plot the quantities determined in part (b), label the axes, and draw the best-fit line to the
data. You may use the blank rows above to record any values you may need to calculate.

Task 3 Radioactive decay is the process of transforming nucleus from unstable state to more stable state. The rate of radioactive decay depends on the specifications of the substance. Depending on that, we can define the half-life as the amount of time needed to convert half of the substance from the unstable radioactive state to the stable state. If you know that the rate of decay for a certain substance is proportional to the amount of the current substance x(t). Formulate a differential equation to express the previous (i) system. (ii) Solve this first order differential equation. (iii) If you know that for a certain substance (carboon-14), 5730 years are needed to convert half of the substance, find the value of the proportional constant.
