Adhesive force and surface tension

AI Thread Summary
In a capillary tube, adhesive forces pull the liquid up while surface tension acts to pull the tube down. According to Newton's third law, these forces should be equal. However, the discussion highlights confusion regarding the nature of adhesive forces and their role in this process. Wetting involves a competition between liquid-solid and air-solid interfacial energies, which complicates the understanding of these forces. The interaction between these forces is crucial for understanding fluid behavior in capillary action.

there is a liquid in a capillary tube. The tube pulls the liquid because of adhesive force and liquid pulls the tube because of surface tension. Will both the forces be equal? according to Newtons third law-yes

I don't understand this. IF this is the case then whatever the substance tube is made up of it will pull the liquid with the same force - which is the force by the surface tension

I don't understand what you mean by 'adhesive force'. Wetting (that is, motion of the three-phase contact line) involves competition between the (in your case) liquid-solid and air-solid interfacial energies.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
