Question:
This is what the lab said to do
- Determine the circumference of the circle.
- For each trial, determine the period of the motion.
- For each trial, calculate the tangential velocity of the stopper.
- For each trial, calculate the experimental centripetal acceleration of the stopper.
- For each trial, calculate the Fg of the each trial of hanging weights (use 9.8m/s2 for ag!). Since this is the FT on the string, this represents the IDEAL FC.
- Determine the percent error of each trial by comparing the ideal Fccreated by the hanging weights to the experimental Fc .
Can you also help me find the circumference of the circle
Mass of Hanging Weight | Tangential Velocity (m/s) | Gravitational force (N) | Centripetal force (m/s2) | Percent error (%) |
50 g | 5.4 m/s | 0.49 | ||
70 g | 6.5 m/s | 0.69 | ||
90 g | 7.6 m/s | 0.88 | ||
110 g | 8.2 m/s | 1.08 | ||
130 g | 8.8 m/s | 1.27 | ||
150 g | 9.1 m/s | 1.47 |
Time of 10 revolutions |
50 g = 8.38 s |
70 g = 6.93 s |
90 g = 5.94 s |
110 g = 5.53 s |
130 g = 5.17 s |
150 g = 4.98 s |
