Effect of Tangential and Normal Forces on Orbital Velocity of Planets

Click For Summary
SUMMARY

The discussion focuses on the effects of tangential and normal forces on the orbital velocity of planets. It concludes that the tangential component of force influences the planet's speed, potentially increasing or decreasing it based on the planet's position along its elliptical orbit. In contrast, the normal component of force, being perpendicular to the direction of motion, does not affect the planet's velocity. Understanding these dynamics is crucial for analyzing orbital mechanics.

PREREQUISITES
  • Understanding of Newton's laws of motion

Homework Statement



What effect will the tangential component of force have on the velocity of the planet?
What effect will the normal component of force have on the velocity of the planet?

Homework Equations


The Attempt at a Solution


1. Since it is parallel to the direction of velocity, maybe it speeds it up/slows it down depending on the location of the planet on the ellipse?

2. No effect since it is perpendicular to the direction of motion.

I'm not really sure if I am right.
