Circular Motion Physics Essay

Open Document

Below is an essay on "Circular Motion Physics" from Anti Essays, your source for research papers, essays, and term paper examples.

I.     Objectives:
a. Examine the relationship between the force that maintains circular motion, the radius, and the tangential speed of a whirling object.
b. Construct a device for measuring the tangential speed of an object undergoing circular motion, and you will determine how the force and the radius affect the tangential speed of the object.

II. Materials:
a. 1.5m nylon cord
b. 2-hole rubber stopper
c. masking tape
d. meter stick
e. PVC tube, about 15cm long and 1cm in diameter
f. set of different masses
g. stopwatch
III.       Data Table #1
Trial Mass of Stopper Hanging Mass Radius T1 T2 T3 Revolutions

1 0.014kg 0.05 kg 0.595m 12.93s 13.10s 14.6s 20
2 0.014kg 0.1 kg 0.595m 11.53s 11.78s 10.8s 20
3 0.014kg 0.15 kg 0.595m 8.59s 9.37s 9.35s 20
4 0.014kg 0.2 kg 0.595m 8.0s 8.03s 7.72s 20
5 0.014kg 0.1 kg 0.765m 12.97s 13.81 ------- 20
6 0.014kg 0.1 kg 0.50m 10.78s 9.72s ------- 20
7 0.014kg 0.1 kg 0.60m 10.0s 10.25s ------- 20
*For the last 3 trials, we only had time to take 2 time intervals.

IV. Analysis and Interpretation
1. Organizing Data- Calculate the weight of the hanging mass for each trial. This weight is the force that maintains circular motion, Fc.

Data Table #2
Trial Hanging Mass F= m(a) Fc
1 0.05 kg 0.05 kg (9.81m/s) 0.49 N
2 0.1 kg 0.1 kg (9.81m/s) 0.981 N
3 0.15 kg 0.15 kg (9.81m/s) 1.47 N
4 0.2 kg 0.2 kg (9.81m/s) 1.90 N
5 0.1 kg 0.1 kg (9.81m/s) 0.981 N
6 0.1 kg 0.1 kg (9.81m/s) 0.981 N
7 0.1 kg 0.1 kg (9.81m/s) 0.981 N

2. Organizing Data- For each trial find the time necessary of one revolution of the stopper by dividing the total time required for 20 revolutions by 20.
                            Data Table #3
Trial T1 T2 T3   Avg. Time
1 12.93s 13.10s 14.6s 13.6s
2 11.53s 11.78s 10.8s 11.4s
3 8.59s 9.37s 9.35s 9.10s
4 8.0s 8.03s 7.72s 7.90s
5 12.97s 13.81 ------- 13.4s
6 10.78s 9.72s ------- 10.3s
7 10.0s 10.25s ------- 10.1s
