    Speed Value
AI Thread Summary
To calculate corrected speed values for an air track experiment, it is essential to understand the impact of air resistance on the cart's motion. The experiment involves measuring the time it takes for the cart to pass through two photogates to determine its speed at various points. The concept of a corrected speed value refers to the theoretical speed the cart would achieve in the absence of air resistance. Newton's first law indicates that an object in motion will remain in motion unless acted upon by an external force, which in this case is air resistance. To obtain the corrected speed, one must analyze the data collected and adjust for the effects of air resistance on the cart's velocity.

what does this mean. I am performing an experiment on an air track with a cart that experiences significant air resistance. For this experiment i think i need to assume it goes at a constant speed. I am supposed to design a method that will allow me to calculate a corrected value with 2 photogates. but i have no idea how to do this because i have no idea what a corrected value is or HOW to obtain it. Any insight into this would be very helpful.

I was thiking of measuring time to pass Photogate A and B at different points to get the speeds at the point and plotting for diff distances to get the deacceleration but then how to i get the corrected value

I'm not sure what you mean. You say the cart experiences significant air resistance but then you say you need to assume it goes at constant speed.

I presume you mean Newton's first law, that, unperturbed, a body will continue in uniform motion.

In your case the air resistance is the perturbation, and I think by a corrected speed value you mean it's speed if there was no air resistance.

Is this correct?
 
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?

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...
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?
