SP15a - SP15d test 2

Question 1

What does elastic mean?

Answer 1

It means the object will return to its original shape when forces are removed

Question 2

What does inelastic mean?

Answer 2

It means the object will not return to its original shape even when the forces are removed

Question 3

What is the extension of the spirng?

Answer 3

it is the change in length when forces are applied

Question 4

What is the spring constant for a spring?

Answer 4

the amount of force need ed to produce an extension of 1 meter

Question 5

State the steps in the investigating springs experiment.

Answer 5

1.Set up the apparatus with the 0 on the ruler being at the bottom of the upstretched spring

2.Measure the length of the spring with no weights hanging on it and write it down’

3.Hang 1 Newton weight on the spring. Record the extension of the spring using the ruler

4.Repeat step 3 until you have found the extension of the spring with 10 different masses

5.Repeat steps 1-4 with a different spring

6.Use results to calculate spring constant for each spring

Question 6

What is the approximate amount of atmospheric pressure?

Answer 6

100000 Pa
