How Do Tangential and Normal Forces Affect Planetary Velocity?

[Gracegao]

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
