String in vertical circular motion

Click For Summary
SUMMARY

In vertical circular motion, an object experiences changes in speed due to the influence of gravitational force. The average speed of the object is noted as 6.1 m/s, but the speed varies at different points in the motion, particularly at the top and bottom of the circular path. Unlike horizontal circular motion, where speed remains constant, vertical circular motion involves acceleration that affects speed due to changes in height and gravitational potential energy. This principle is exemplified in scenarios such as roller coasters, where speed fluctuates during ascents and descents.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with concepts of gravitational force
  • Knowledge of circular motion dynamics
  • Basic principles of energy conservation in physics
NEXT STEPS
  • Study the effects of gravitational force on vertical circular motion
  • Explore the concept of centripetal acceleration in different motion types
  • Investigate energy transformations in roller coasters and similar systems
  • Learn about the mathematical modeling of circular motion using physics equations
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of motion, particularly in scenarios involving vertical circular paths and the effects of gravity on speed.

If an object is tied to a string in vertical circular motion (yes, I mean vertical as in the string has the force of gravity acting on it), does it actually change speed? I was given a question where the 'average speed' of an object in vertical circular motion was 6.1 m/s, and then they wanted me to find the point of least speed. So I guess speed changes then? But why? I was taught that the speed of an object in circular motion is always the same but the object is accelerating because direction changes. Does this ONLY apply to horizontal circular motion?

no sir, yes sir. The speed in say a loop de loop roller coaster most certainly changes with uphill or downhill part of the trajectory. Yet its still executing circular motion.
 
Alright, thanks for your help.
