SUMMARY

The discussion focuses on the types of acceleration in the rotational movement of rigid bodies, specifically distinguishing between translational and rotational acceleration. Key equations include linear acceleration as a = dV/dt, angular acceleration α = dω/dt, and the relationship a = rα for rotational acceleration. Participants clarify that centripetal acceleration is given by a = ω²r, while tangential acceleration is defined as a_t = r * (dω/dt). The conversation emphasizes the need for a solid understanding of these concepts, often referencing external resources for further learning.

PREREQUISITES
  • Understanding of basic physics concepts, including motion and forces
  • Familiarity with angular velocity and angular acceleration
  • Knowledge of the equations of motion for rigid bodies
  • Basic calculus for derivatives and integrals
NEXT STEPS
  • Study the derivation of the equations for linear and angular acceleration
  • Learn about centripetal and tangential acceleration in circular motion
  • Explore the relationship between linear and angular quantities in rigid body dynamics
  • Review resources on rotational motion, such as the Wikipedia page on circular motion
USEFUL FOR

Students of physics, mechanical engineers, and anyone interested in understanding the dynamics of rotational motion and its applications in real-world scenarios.

So we have two accelerations, the tangential acceleration and the centripetal acceleration.
The centripetal is the one that makes the particle move in a circular route.
The tangential is the one that makes the particle move faster/slower on the circular route.
Right?

And the first one is v^2/r.
And the second is γ/r.
Right?

I don't understand why it should take tons of posts for a comprehensive and simple reply like this.

Will someone eventually post a 'comprehensive' reply instead of posting bits?

You have a misconception about how PF works.

A "comprehensive reply" is open-ended; you could be asking for a course in physics 101, and that's way outside the scope of PF. All we can do is point you in the right direction; you have to do the work.

Several posters in this thread have given you good links to sources of information. Please read them, and take some time to build your own understanding. Then, if you have specific questions about something you find, you can start a new thread asking that specific question.

This thread will remain closed.
