Frame of Reference: Constant Velocity & Inertiality

AI Thread Summary
A frame of reference moving with constant velocity relative to an inertial frame is itself considered inertial. This is because an object maintaining constant velocity in one frame will also exhibit constant velocity in another frame moving at the same rate. The principle of relativity asserts that the laws of physics remain consistent across all inertial frames. Therefore, the motion observed in both frames will align, confirming the inertial nature of the moving frame. Understanding this concept is crucial for analyzing motion in different reference frames.

a frame of reference is moving with a constant velocity with respect to a inertial frame of reference,then moving frame will be inertial itself?

Yes, can you show why? Try beginning by showing that if an object is moving with constant velocity \vec{v} in the first frame then it will also move with a constant velocity in the second.
 

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?
