Hey so I am learning physics on Khan academy and they had a video on Pitot tubes: https://www.khanacademy.org/science/physics/fluids/fluid-dynamics/v/venturi-effect-and-pitot-tubes I had a question. I understand that the lower part of the pitot tube in the video is measuring the pressure...

These are the diagrams I had? So as acceleration increases in the direction of the center, the velocity increases perpendicular to the circle to make up for the increased acceleration and in turn making sure the car doesn't just fall to the center correct? I know they are inter related by the...

Two questions I had: 1. How is the force of friction of the tires pointed inwards to cause centripetal acceleration? If the tire is rotated when trying to turn, the car is still traveling with a velocity perpendicular to the circle and force of friction would still be counteracting the...

Thanks! I didn't know that G is the same between any two objects. That was what was confusing me!

They would have to be equal though? Isn't the force exerted by the moon's gravitation on the Earth going to be less than the force exerted by the Earth's gravitation on the moon (since gravity is less on the moon)?

Thanks for the help. I was so lost before this. :)

In relation to two objects with a gravitational field on them (i.e. a planet and its moon), would there be two pairs of partner forces (the force of gravity exerted from each object and the resulting partner force from each force of gravity)? For example with the Earth and moon: 1. Force of...

So in essence, because the reversible system is doing some work pushing the piston W + some amount of the granules w (changing as you remove granules) up throughout the process, while the irreversible is just pushing the piston W up through the whole process, the work done by irreversible is...

I am learning physics on khan academy and they do a proof to show that delta G for a reversible reaction is negative and how for a irreversible reaction it is positive. However in the proof, they assume that the heat put in by the isotherm is less for an irreversible reaction compared with a...
