Components of Net Force

Components of Net Force#

Part 1#

The image shows the free-body diagram of an object in circular motion with speed v and radius r. The net force is along the radial direction. The component of Newton’s second law along the radial direction is:

Circular Motion FBD

Answer Section#

  • nβ†’+fsβ†’=maβ†’

  • nβ†’βˆ’fsβ†’=mv2arβ†’

  • ncos(ΞΈ)+fs=mv2a

  • ncos(ΞΈ)βˆ’fs=mv2a

  • nrβ†’βˆ’fs,rβ†’=marβ†’
