Lab: Factors Affecting Circular Motion
Purpose: See in page
Hypothesis: See in page
Procedure:
- The rubber stopper was secured to a rope
- The rope was fed through the glass tube
- The length of rope was measured to 20cm
- The alligator clip was clipped 2cm below glass tube as indicator
- A steel washer was secured to bottom of rope
- The rubber stopper was swung and maintained a radius of 20cm
- The time for rubber stopper to achieve 10 cycles was recorded
- Steps 6 to 7 were repeated two times for two extra trials
- 2 steel washers were added to the bottom of the rope
- Steps 6 to 9 were repeated three more times
- The time for 10 cycles was averaged out
Observations:
Number of Washers | Mass (kg) ± 0.0003 | Time for 10 rotations (s) ± 0.2 | Frequency ( Hz ) | Force FT (N) | √Force √F (√N) | |||
Trial 1 | Trial 2 | Trial 3 | Average | |||||
1 | 0.00713 | 8.1 | 8.0 | 8.1 | 8.0 | 1.25 | 0.07 | 0.26 |
3 | 0.02170 | 6.0 | 6.2 | 6.1 | 6.1 | 1.64 | 0.21 | 0.46 |
5 | 0.03660 | 5.6 | 5.9 | 5.7 | 5.71 | 1.75 | 0.36 | 0.60 |
7 | 0.05100 | 4.2 | 4.3 | 4.6 | 4.3 | 2.32 | 0.50 | 0.71 |
9 | 0.06600 | 3.9 | 4.1 | 4.1 | 4.0 | 2.50 | 0.65 | 0.81 |
Sample Calculations:
Force = mg
For 1 Washer, (0.00713 kg x 9.8 m/s2) = 0.07
Frequency = , where t is time for 10 rotations[pic 1]
