Can Resistance Exceed a Mass's Top Speed in Theory?

AI Thread Summary
The discussion centers on whether resistance can exceed the top speed of a moving mass. It is clarified that a moving mass does not have a definitive "highest speed," as it can always be accelerated further, even near the speed of light. The term "resistance speed" is questioned, indicating a lack of clarity on what it means. The conversation emphasizes the continuous potential for acceleration rather than a fixed speed limit. Overall, the concept of resistance in relation to speed remains ambiguous and requires further definition.

If some mass is moving at it's highest speed is there anything that can prove that the resistance to that mass should actually exceed the speed of that mass' top speed to resist? Elementary question for you brainiacs :) but I really want to know if resistance speed might in theory exceed said mass top speed for a reason! Anyone know of a law or theory regarding this? I am young to science so please go easy on me, thank you

A moving mass has no "highest speed". Even if it is going close to the speed of light, you can always accelerate it and it will go a little bit faster. I have no idea what you mean by "resistance speed".
 

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 '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 '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?
