Hookes Law

Question 1

hookes law states that

Answer 1

the extension of a spring is proportional to the force applied to it

Question 2

how to calculate the spring constant?

Answer 2

1 / gradient

Question 3

what is the length of an unstretched spring called?

Answer 3

natural length

Question 4

experiment for hookes law

Answer 4

1) measure the natural length of the spring (jsing a ruler) when no load is applied.
2) add one slotted mass at a time, allowing the spring to come to rest each time. measure the new length of the spring. the extension is the change in length from the natural length.

Question 5

what is the formula for hooke‘s law?

Answer 5

force = constant x extension

Question 6

describe a hookes law graph

Answer 6

1) the first part of the graph shows hookes law being obeyed: there is a straight line (going through the origin) relationship between force and extension, showing they are proportional
2) point E is the elastic limit/ limit of proportionality of the spring. as the force applied increases, extension levels off as the material begins to be permanently stretched and its natural length will haved increased.
