Acceleration & Rotational Motion: What's the Link?

AI Thread Summary
Acceleration and rotational motion are linked through their behavior in uniform and non-uniform motion. In uniform motion, both acceleration and rotational motion remain constant, while in non-uniform motion, they change over time. This relationship clarifies concepts such as the pendulum's movement. Understanding these dynamics enhances comprehension of motion in physics. The discussion highlights the importance of recognizing how these two types of motion interact.

Yep! :smile:

They are all constant in uniform motion.
In non-uniform motion they vary with time.
 


Ah, that's interesting! You know, now I fully understand that pendulum exercise from before! :)

Thanks to this little comment

In non-uniform motion they vary with time.

Thanks!
 

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?
