Hello I need some help with this lab. JUST FROM THE ANALYSIS QUESTIONS! Everything before that is soyou can know what the lab is about. I collected all the data needed already, it's highlighted in red. There is also a diagram of how the set up should look like. If you could help me out that would be great.
Purpose: to use a pendulum to discover the relationship between kinetic energy, Ex. and Data for the Lab: Trail #1 gravitational potential energy, Eg- 20cm = 07.58s Length of string = 64.0cm Hypothesis: Predict the relationship between kinetic energy, Ex, and gravitational potential 15cm = 08.13s Mass of weight = 200.0g energy, DEg. 10cm = 07.67s Equipment: weight string retort stand clamp scale Procedure: 1. Measure the mass of the weight. 2. Attach the clamp near the top of the retort stand. 3. Use the string to suspend the weight from the clamp so that it can swing freely. 4. Measure the length of the string from the clamp to the centre of the weight. 5. Move the weight about 20 cm away from vertical and measure the horizontal deflection. 6. Release the weight. Record and time 5 cycles. A cycle is a complete trip from the release point back to the release point. You may should repeat until you get reliable times and recordings. 7. Reduce the horizontal deflection by about 5 cm and repeat steps 5 and 6. 8. Reduce the horizontal deflection by about another 5 cm and repeat steps 5 and 6. length Analysis: . Determine the difference between the length of the adjacent side and the pendulum length. This is the change in height, Oh. 4. Determine the gravitational potential energy, Eg, at maximum deflection for each trial. Determine the time needed for the weight to complete 14 of a cycle, the arc from maximum deflection to the bottom. Determine the circumference of the circle that the pendulum would travel if it could complete a Ah circle. The pendulum length represents the radius. 7. Determine the length of the are represented by a % cycle for each trial. Use the angle of deflection and the circumference. 8. Determine the speed of the weight at the bottom of its arc for each trial. Remember that 14 cycle horizontal deflection 1/4 cycle arc length divided by the time for a 14 cycle represents average speed, Van not the speed at the bottom of the arc. 9. Determine the kinetic energy, Ek. at at the bottom of the arc for each trial. 10. Explain what happens to the gravitational potential energy and the kinetic energy as the weight travels through a cycle. Conclusion: What is the relationship between kinetic energy, Ex and gravitational potential energy, DEg
