Variables:
- Independent variable: Height of the ramp
- Dependent variable: Velocity (kinetic energy) of the object rolling down the ramp
Hypothesis:
As the height of the ramp increases, the velocity (kinetic energy) of the object rolling down it will also increase. This is because a higher ramp will provide the object with more potential energy, which will be converted into kinetic energy as it rolls down the ramp.
Experimental setup:
1. Set up ramps of different heights (e.g. 1m, 2m, 3m) on a flat surface.
2. Place an object (e.g. a ball) at the top of each ramp.
3. Release the object from the same starting point on each ramp and measure its velocity (kinetic energy) at the bottom using a stopwatch and measuring tape.
4. Repeat the experiment multiple times for each ramp height to ensure accuracy.
Data analysis:
Plot a graph of ramp height (independent variable) versus velocity (dependent variable) to analyze the relationship between the two. Compare the velocities of the object for different ramp heights to determine if there is a significant effect of ramp height on the velocity of the object rolling down it.
Conclusion:
Based on the results of the experiment, determine whether the hypothesis was supported or refuted. Discuss any potential sources of error and suggest ways to improve the experiment for future studies.
Constants: 1.3.5. 2.4.6.
