# Lab Report
**Energy**
### Introduction
1. **Purpose of the Experiment:**
The purpose of the experiment was to investigate the relationship between the height from which a ball was dropped, its potential energy at that height, and the kinetic energy it possessed as it traveled down a ramp. This experiment aimed to demonstrate the principles of conservation of energy, particularly how potential energy is converted into kinetic energy.
2. **Variables:**
- **Independent Variable:** The drop height on the ramp (measured in meters), which was manipulated by changing the height from which the ball was released.
- **Dependent Variables:** The potential energy (in joules), time to travel 1.0 m (in seconds), speed (in meters per second), and kinetic energy (in joules) of the ball at the bottom of the ramp, which were measured as the outcome of the experiment.
- **Control Variables:** The mass of the ball was kept constant (for example, 0.5 kg), the type of ramp surface was consistent, and environmental factors such as air resistance were minimized.
### Experimental Methods
1. **Tools Used to Collect Data:**
To collect the data, we used the following tools:
- A digital scale to measure the mass of the ball (kg).
- A ruler or tape measure to determine the drop height (m).
- A stopwatch to measure the time taken for the ball to travel 1.0 m (s).
- A motion sensor or speed measurement tool to calculate the speed of the ball (m/s).
- Software or a calculator to compute potential energy and kinetic energy.
2. **Procedure:**
The procedure followed to collect data for the first part of the experiment included the following steps:
- Measure and record the mass of the ball to ensure it remained constant throughout the experiment.
- Set up the ramp at various heights (0.5 m, 1.0 m, 1.5 m, 2.0 m, 2.5 m, and 3.0 m), ensuring accurate measurements.
- Release the ball from the designated height without any initial push, allowing it to roll down the ramp.
- Use the stopwatch to measure the time it took for the ball to travel a distance of 1.0 m down the ramp and record the time.
- Calculate the potential energy using the formula PE = mass × gravity × height (PE = mgh) for each height.
- Measure the speed of the ball at the bottom of the ramp and calculate the kinetic energy using the formula KE = 0.5 × mass × speed².
- Repeat the measurements for each height at least three times to ensure accuracy and reliability, recording all observations in a data table.
### Data and Observations

**Table 1. Measurements Taken from a Simulation of a [insert mass value] kg Ball Released from Various Heights on a Ramp**
| Mass of ball (kg) | Drop height on ramp (m) | Potential energy (J) | Time to travel 1.0 m (s) | Speed (m/s) | Kinetic energy (J) |
