Hooke’s Law

2
Hooke’s Law The force exerted on an object (F) is proportional to the amount of stretch or compression (x) and the spring constant (k) F = Newtons x = meters k = N/m

3
Hooke’s Law Hooke’s Law mainly applies to elastic objects like springs and rubber bands We will mainly focus on springs All elastic objects obey Hooke’s Law until they reach their ELASTIC LIMIT and become deformed

4
EXAMPLES A spring with a spring constant of 10 newtons per meter is stretched 0.5 meters. How much force is applied to the spring? A spring with a spring constant of 15 newtons per meter is compressed with a force of 4.5 newtons. How far will the spring compress?

5
EXAMPLES A spring is stretched a distance of 0.4 meters with a force of 20 newtons. Calculate the spring constant of the spring.

6
**SUMMARY Which objects does Hooke’s Law apply to? Equation?**

Which letter represents the spring constant? Units for the spring constant? Which kind of force acts on a spring if something is hung on the spring?
