Can I add error bars for one measurement?
let's say that we have energy value for each temperature degree, and when plotting the energy vs. temperature, we get a scatter plot. Can we add error bars to the point in this plot? or does the experiment has to be repeated in order to get multiple trials.
In other words, Standard deviation and standard error are used in calculation and generating error bars. How these quantities are calculated if I only do the experiment one time (no repeating) and get one measured value each time.
Homework Answers
To get error from just one reading you need to know the absolute value. With which you can find the difference or error.
Else you will require multiple readings. Then its average will act as the absolute value

Error Propagation What is error propagation? A question in error propagation is that when we take a product of measurements we do what with the uncertainties? Should our uncertainties get bigger or smaller as they propagate through the formulas? Take a square and measure one side. What happens to the uncertainties when you calculate Area? Can this be beneficial when our product contains measurements of different units? The rule is to find the relative uncertainty in a product of measurements...

Below is an image from a double slit experiment obtained by shining a laser through one. I used a He-Ne Laser, wavelength = 632.8 nm, and shined through two slits whose separation distance is d = 0.250 mm. The light was shined upon a sheet of paper taped to the wall and was 10.0 ft 4.00 inches away from the double slit. I circled the bright spots (constructive interference) and identified the central maximum (m = 0). I saved the...

I need help for numbers 1 and 3. For number one I
measured the height of the track at angle. One of the heights was
.082m. hypotenuse 1.013m. I did sin^-1(.082/1.013) and got 4.64
degrees. I used a sensor and aquired data for change in v and t as
a glider fell down the track. I calculated the acceleration at that
height and angle as -10.18 m/s^2. final V was 1.48, initial V .687.
final t=.0675, initial t= .1454.

I need a Python code for this problem.
We can use python's array slicing in many ways, and here is just one example. To take the forward derivative of an array y, we use (y[i+1] - y[i])/dx For example, if dx=1 , we might write a derivative routine as yderiv = zeros (len(y)-1) for i in range(len(y)-1): yderiv[i] = y(i+1] - y[i] Note that here, yderiv is one element shorter than y -- this is because you need 2 points...
