Effect of Tangential and Normal Forces on Orbital Velocity of Planets

AI Thread Summary
The tangential component of force affects a planet's velocity by either increasing or decreasing it, depending on the planet's position in its elliptical orbit. In contrast, the normal component of force does not influence the planet's velocity, as it acts perpendicular to the direction of motion. The discussion highlights the importance of understanding how forces interact with velocity vectors in orbital mechanics. Additionally, the force that maintains a planet's orbit is directed towards the center of the orbiting body, providing the necessary centripetal force. Understanding these dynamics is crucial for analyzing orbital 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.

What is the direction of the force that holds a planet in it's orbit?

Note: velocity is a vector.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
