AI Thread Summary
The freefall velocity formula, V = √(2gΔy), is confirmed to be legitimate for calculating the speed of an object falling from rest over a distance without friction. The formula uses small g, which represents the acceleration due to gravity (approximately 9.8 m/s²). It accurately determines the velocity after falling a specified distance. The discussion clarifies the distinction between small g and the universal gravitational constant, G. Overall, the formula is validated for its intended use in freefall scenarios.

hi i was wondering if this formula is legitimate. it finds velocity when there is no friction and no time involved.

<br /> \sqrt{2\ G \Delta\ x_{y}}<br /> =V

G is 9.8m/s

thanks, eliot

It's legit. It gives you the speed after falling the given distance, starting from rest. (Use small g for the acceleration due to gravity; big G usually stands for the universal gravitational constant.)
 
o yeah small g. ok thanks, i appreciate it. :)
 

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?
