How Do Tangential and Normal Forces Affect Planetary Velocity?

Click For Summary
SUMMARY

The discussion focuses on the effects of tangential and normal forces on planetary velocity, specifically in the context of Kepler's laws. It is established that the tangential force directly alters the velocity of a planet, while the normal force primarily affects the direction of the planet's motion. The relationship between tangential force and velocity is proportional, confirming the participant's understanding of these forces. Additionally, Kepler's second law, which states that equal areas are swept out in equal times, is referenced as a foundational principle in this context.

PREREQUISITES
  • Understanding of Kepler's laws of planetary motion
  • Basic physics concepts of force and motion
  • Knowledge of tangential and normal forces
  • Familiarity with vector components in physics
NEXT STEPS
  • Study Kepler's laws in detail, focusing on their implications for planetary motion
  • Learn about the mathematical representation of tangential and normal forces
  • Explore the concept of centripetal force and its relation to planetary orbits
  • Investigate the effects of gravitational forces on planetary velocity
USEFUL FOR

Students of physics, educators teaching planetary motion, and anyone interested in the dynamics of celestial bodies and their movements.

Kepler's law questions

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


I think that the tangential force change the value of the velocity, and they are in proportional relationship
The normal force change the direction of the planet.
I'm right about these? If not, can you explain the right answers? thank you very much

If memory serves me, Kepler's second law is equal time = equal area
