Centripetal Force & Acceleration

This topic is apart of the HSC Physics syllabus Module 5: Advanced Mechanics.

Learn to investigate the orbital motion of planets and artificial satellites when applying the relationships between the following quantities:

  • Centripetal force
  • Centripetal acceleration

 

Centripetal Force & Acceleration

Centripetal Force is the forced direct towards the centre of the orbit. It is the following equation:

F = \frac{mv^2}{r}
  • F is the force
  • m is the mass
  • v is the velocity
  • r is the radius

Centripetal Acceleration comes from equating the centripetal force to the regular force formula F =ma.
