    Frames Inertial
AI Thread Summary
Inertial reference frames are defined as those free from external forces, where Newton's laws of motion apply. Non-inertial reference frames experience acceleration and are influenced by fictitious forces, such as the Coriolis force. The discussion clarifies that inertial frames are not restricted to Euclidean space, as they can exist in various geometrical contexts. The distinction between these frames is crucial for understanding dynamics and motion. Overall, the conversation emphasizes the fundamental differences in how forces and motion are perceived in inertial versus non-inertial frames.

Could someone explain me in detail the differences between an inertial reference frame and a non-inertial reference frame? Are inertial frames restricted to Euclidean space?

Inertial reference frame is a reference frame free of all external forces and non-inertial reference frame is the just the opposite.
 
inertial frame is the one where Newton's laws r applicable.and u can guess by this non inertial frames.if any frame having accelaration it does fall under non inertial frame where coriolis force come into play
 

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?
