Hooke’s Law

Question 1

What does hooke’s law state

Answer 1

The extension of a spring is directly property to the force applied

Question 2

When does hooke’s law work

Answer 2

Any time before the spring has reached the proportionality limit

Question 3

When does the spring change from elastic deformation to plastic deformation

Answer 3

At the elastic limit

Question 4

What is plastic deformation

Answer 4

When the force is released, the object will not return to it’s original shape

Question 5

What is elastic deformation

Answer 5

When the force is released the object will return to its original shape

Question 6

What is the equation for hooke’s law

Answer 6

F = K x delta L

F = force
Delta L = extension
K = Spring Comstant

Question 7

What does the area under a hooke’s law graph show

Answer 7

The elastic potential energy / work done

Question 8

How do you calculate elastic potential energy?

Answer 8

1/2 x f x delta L
OR
1/2 x k x delta L ^2
