SUMMARY

The discussion focuses on calculating centripetal acceleration using a rotational platform with a mass of 457 grams and a radius of 16 cm. The user provided the equation for velocity, V = 2π(r^2)/t * 100, and the equation for force, F = mV^2/r. Despite following these equations, the user is unable to achieve the expected counter force of 5.4 N. The calculations need to be verified and corrected to align with the expected results.

PREREQUISITES
  • Understanding of centripetal acceleration and its equations
  • Familiarity with basic physics concepts such as mass, radius, and force
  • Ability to perform calculations involving π (pi) and unit conversions
  • Knowledge of rotational motion principles
NEXT STEPS
  • Verify the velocity calculation using the equation V = 2π(r^2)/t * 100
  • Recalculate the force using the correct velocity in the equation F = mV^2/r
  • Explore the relationship between mass, radius, and centripetal force
  • Research common errors in centripetal force calculations and how to avoid them
USEFUL FOR

Physics students, educators, and anyone involved in experiments related to rotational motion and centripetal force calculations.

Using a rotational platform I found the following values..
Mass of bob: 457 grams
Radius: 16 cm
time to make 100 rotations: 67.4 seconds
I need to find the velocity and was given the following equation V=2pi(r^2)/t *100
Once I find the velocity i need to plug that into the following equation to find force
F=mV^2/r

The counter force in the experiment was 5.4 N and i can't get anywhere near there. Can someone help me with this problem please.
