Velocity and acc. of circular motion

Click For Summary

Discussion Overview

The discussion revolves around real-life applications of velocity and acceleration in circular motion, prompted by a request for examples suitable for an essay. Participants explore various scenarios where these concepts are relevant, including both everyday and specialized contexts.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant suggests a merry-go-round and dirt flying off a wheel as examples of circular motion.
  • Another participant mentions tornadoes but expresses uncertainty about their relevance.
  • A participant proposes that knowledge of velocity and acceleration in circular motion is essential for race car drivers and fast-driving individuals.
  • Fighter pilots are highlighted as another group that likely considers these concepts when making tight turns in aircraft.
  • One participant asserts that nearly all activities involve some element of rotational motion and encourages finding a relatable example to write about.
  • A later reply emphasizes the extreme forces fighter pilots endure during tight turns, noting the high 'g' forces they can withstand compared to the general population.

Areas of Agreement / Disagreement

Participants generally agree that circular motion is prevalent in various contexts, but there is no consensus on specific examples or their significance.

Contextual Notes

Some examples mentioned may rely on idealized conditions or assumptions about human tolerance to forces, which are not universally applicable.

Who May Find This Useful

This discussion may be useful for students exploring practical applications of physics concepts, particularly in relation to circular motion and its effects in real-world scenarios.

hi,
can someone give me some real life examples of where the knowledge of velocity and acceleration of circular motion comes in handy? i can't even think of one and my teacher asked us to write an essay on it. thanks a lot.
 
Physics news on Phys.org
a merry-go-round? dirt flying off a wheel?

a tornado? Though I don't know how that would come in handy...
 
While I doubt that it is necessary to calculate the forces exactly, surely some knowledge of how velocity, acceleration, and force going around an arc is essential to race car driver (or those of us who just drive fast!).

Fighter pilots who make fast turns probably think a lot about that also.
 
actually almost everything you do has some element of rotational motion in it. My advice to you would be to find *anything* you like to write about and then find some aspect of rotational motion and write about it.

Actually, is there an example that can be recreated on Earth (no "ideal" models) where there is no rotational motion?

Nice example. :smile:

Fighter pilots can be trained to cope with about 11 'g' when undergoing tight turns in aircraft - most of us would pass out at about half of that!
