Hooke's Law Flashcards
1
Q
What does a string/spring fo when it is compressed?
A
It exerts an outward force which is called thrust.
2
Q
What is hooke’s law?
A
Tension is proportional to extension and thrust is proportional to compression.
3
Q
What are the three formulas for hooke’s law?What are the units?
A
F=kx k is n/m
F=lambda x/l lambda is n
F=EA/l E is modulus of elasticity. E is N/m^2.
4
Q
How to find the elastic potential energy stored in a spring?
A
E=1/2Lambdax^2/l
