What Causes the Tides on Earth?

AI Thread Summary
The discussion centers on the gravitational forces that cause tides on Earth, primarily focusing on the moon's gravitational pull. Participants acknowledge that while the moon is the main contributor, the sun's gravitational force also plays a significant role. There is some confusion about the Earth's gravitational influence and the relevance of other planets like Mars and Venus, which exert minimal force. The consensus is that the three main forces affecting tides are those from the moon, the sun, and the Earth itself. Understanding these influences is crucial for accurately answering related homework questions.

What three gravitational forces act on the oceans of the Earth to cause the tides?

The Attempt at a Solution


Hi. I was wondering if anyone could help me with this question.
Everyone knows it is the gravitational force of the moon, but that's about it. :frown:
Could the gravitational force of the Earth and of the sun also be involved?
But then why not add Mars and all the other planets, as they exert a force too, more or less.
I also found answers such as the gravitational force of the moon, the sun and inertia or Earth's rotation but that's not a gravitational force.
Thank you.

Check the relative influence of the Earth, Moon and Sun, and perhaps look at the influence of Mars and Venus.
 
This question had so many marks.
After researching, I decided on the moon, the sun and the earth.
Thank you for the suggestion.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
