I need help filling out the chart on the period of pendulum. Can you help.
- Investigate: Conduct similar controlled experiments on the effects of length, gravitational acceleration, and angle on the pendulum period. Record your results below.
Length experiment
m (kg) | L (m) | g (m/s2) | () | Time for 10 swings (s) | Period (s) |
1 | .5 | 9.8 | 20 | ||
1 | 1.75 | 9.8 | 20 |
Gravitation experiment
m (kg) | L (m) | g (m/s2) | () | Time for 10 swings (s) | Period (s) |
1 | 2 | 9.8 | 20 | 28.40 | 2.84 |
1 | 2 | 1.6 | 20 |
Angle experiment
m (kg) | L (m) | g (m/s2) | () | Time for 10 swings (s) | Period (s) |
1 | 2 | 9.8 | 15 | ||
1 | 2 | 9.8 | 90 |
- Analyze: Look at your data.
