Elasticity

Question 1

What do you need for elastic deformation

Answer 1

At least 2 forces applied to an object in different directions

Question 2

What is elastic deformation

Answer 2

If you remove the applied forces from an object and it goes back to the original shape and length

Question 3

What is inelastic deformation

Answer 3

If the applied forces are removed and the object doesn’t return to its original shape and length

Question 4

What is the equation for spring constant

Answer 4

F=ke
F - force (N)
K - spring constant (N/m)
E - extension (m)

Question 5

Hookes law

Answer 5

The extension of an object is directly proportional to the force applied to it (provided the limit of proportionality is not exceeded)

Question 6

What is the limit of proportionality

Answer 6

The limit to the amount of force you can apply to an object for the extension to keep increasing proportionally

Question 7

What is the gradient of a force/extension graph

Answer 7

The spring constant
