Draw a free body diagram of each object in centripetal acceleration

Click For Summary
SUMMARY

This discussion focuses on drawing free body diagrams for objects experiencing centripetal acceleration, specifically the Moon in orbit around Earth, an electron in orbit around a nucleus, and a snowboarder navigating a circular arc. The centripetal force for the Moon is identified as the gravitational force exerted by Earth, while the force acting on the electron is also referred to as gravitational, although this is a misnomer. For the snowboarder, both normal force (Fn) and gravitational force (Fg) are present, with Fg needing to exceed Fn to provide the necessary centripetal force (Fc).

PREREQUISITES
  • Understanding of centripetal acceleration and its implications.
  • Knowledge of free body diagram construction.
  • Familiarity with gravitational force concepts.
  • Basic physics principles related to circular motion.
NEXT STEPS
  • Study the principles of centripetal force in circular motion.
  • Learn how to accurately draw free body diagrams for various forces.
  • Investigate the differences between gravitational force and other forces in atomic structures.
  • Explore the effects of centripetal acceleration on different objects in motion.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and circular motion, as well as educators looking for examples of free body diagrams in centripetal acceleration scenarios.

Homework Statement


Draw a free body diagram of each object in Italics, that is in centripetal acceleration, and name the force causing this centripetal acceleration.
a. Moon in circular orbit around Earth.
b. Electron in circular orbit around nucleus of atom .
c. Snowboarder slides over top of a bump that is in the shape of a circular arc.


Homework Equations



N/A

The Attempt at a Solution



a. See Pic 1. The force is force of gravity exerted by the Earth?
b. Same as Pic 1. The force is Fg exerted by the atom?
c. There is a Fn and Fg on the snowboarder, I think. The Fg must be greater such that it can 'supply' the required Fc (centripetal force).

Thanks so much in advance. :) :)

yep! that all looks correct to me :)

The notation 'Fg' suggests gravity. It's not that.
