investigating springs

Question 1

part 1 - Apparatus

Answer 1

• Set up the apparatus and have plenty of extra masses and measure mass of each and calculate weight. w=mg

Question 2

How do you check that your masses are a good size?
part 2

Answer 2

• do a quick pilot experiment
  ⭐ use an identical spring to the one you’ve been testing and load it with masses one at a time with a total of 5.Measure extension each time you add another mass
  ⭐work out the increase in extension of the spring for each of your masses, if any cause a bigger increase than previous one, you’ve gone past the limit of proportionality .
  ⭐if this happens you’ll need to use smaller masses

Question 3

part 3 (1 to 4)

Answer 3

1) measure the natural length of the spring with a mm ruler clamped the the stand making sure you take the reading at eye level and add a marker to the bottom of the spring so make sure the reading is more accurate
2) add a mass to the spring and allow it to come to rest. Record the mass and the new length of the spring. The extension is the change in length

3) ⭐Repeat this process until you have enough measurements.
4) plot a force- extension graph of your results
(only curve if exceed limit of proportionality

Question 4

part 4

Answer 4

• When the line of best fit is straight = linear relationship f=ke
• when the line begins to bend = the relationship is now non-linear, spring stretches more

Question 5

How do you work out energy stored for linear relationship?

Answer 5

Ee = 1/2 Ke^2

Question 6

How do you work out energy stored in a springs elastic potential energy store for elastic deformation

Answer 6

Ee = 1/2 Ke^2
