Centripetal force experiment lab

SUMMARY

The discussion centers on the relationships between mass, velocity, radius, and centripetal force in a centripetal force experiment. Participants explore how varying these parameters affects the motion of a whirling object. Key inquiries include the impact of squaring velocity on graph shapes and the practical aspects of conducting the lab experiment. The conversation emphasizes the need for clear explanations over mere formula rearrangements.

PREREQUISITES
  • Understanding of centripetal force concepts
  • Familiarity with circular motion dynamics
  • Basic graphing skills for experimental data
  • Knowledge of how to manipulate variables in a physics lab setting
NEXT STEPS

What is the relationship between the mass and velocity of a whirling object? base of graph relationship

What is the relationship between the radius of revolution and the velocity of a whirling object?

What is the relationship between the velocity of a whirling object and the centripetal force that is exerted on it?

I graphed centripetal force vs velocites, and radii vs velcoites, homework would the shape of graphs change if I square the v? I'm assuming straighter instead of curve?

Please don't give me the equations and rearrange them etc... This is for a lab, I'm not really understanding these questions, I have tried book, google(ppl only just rearrange the euqations, doen't explain anything, I don't think the teacher wants to see equations rearranged unless expalained by WORDS)

What did you do in the lab? What measurements do you have?
The first question seems to be asking about an experiment where the mass and speed of an object in circular motion both change. It is easy to change the speed, but I'm curious how you changed the mass.

Of course the pioneers figured out the formulas from the experiment, but sometimes it took them years to do it. You might want to peak at the formula for what you did in the experiment to get a hint on what to graph to get a nice straight line graph for which a formula can easily be written.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
