Hooke’s Law Flashcards
1
Q
What is extension
A
When an object increases in length
2
Q
What is compression
A
When an object decreases in length
3
Q
What is hooke’s law and its equation
A
the extension of a spring is directly proportional to the applied force up to the limit of proportionality.
Force = Spring constant x Extension
F = ke
F = applied force - N
K= stiffness constant of the spring - N/m
e= Extension of the string - e/m
4
Q
What happens if the units for length are in mm or cm?
A
e = mm
K = N/mm
e = cm
K = N/cm
5
Q
If a is directly proportional to b on a graph what must happen
A
Straight line
Passing through the origin
6
Q
Where on a graph does hooke’s law apply
A
On the straight section, up to the “limit of proportionality”
