Describe the investigation you will conduct to find the relationship between the centripetal force and mass.

1. Objective: The main objective of this investigation is to find the relationship between centripetal force and mass.

2. Materials Needed: A circular track or turntable, a mass set, a string, a stopwatch, a ruler, and a spring scale.

3. Procedure:

   • Step 1: Set up the circular track or turntable. Attach one end of the string to the mass and the other end to the spring scale. Place the mass on the track.

   • Step 2: Start rotating the mass around the circular track. Make sure the string is taut and the mass is moving in a circular path.

   • Step 3: Use the spring scale to measure the force required to keep the mass moving in a circular path. This is the centripetal force.

   • Step 4: Record the mass of the object and the corresponding centripetal force.

   • Step 5: Repeat steps 2-4 with different masses. Make sure to keep the radius and speed of the circular motion constant.

4. Data Analysis: Plot a graph of the centripetal force (y-axis) against the mass (x-axis). If the points on the graph form a straight line passing through the origin, then the centripetal force is directly proportional to the mass.

5. Conclusion: From the graph, determine the relationship between the centripetal force and the mass. If the graph is a straight line, it indicates that the centripetal force is directly proportional to the mass. If the graph is a curve, it indicates that the relationship is not linear.

Remember, safety is paramount during the experiment. Always ensure the mass is securely attached to the string to prevent it from flying off during the experiment.
