In this graph, the relationship between force and extension is linear.
In this graph, the relationship between force and extension is non-linear.
In this graph, the relationship between force and extension is directly proportional.
In this graph, there is no relationship between force and extension.
The graph shows the relationship between force and extension as a spring is extended. What is another name for point A?
Point A is the elastic limit
Point A is the elastic summet
Point A is the plastic limit

Which statement most accurately represents Hooke's Law?
a) The stretch of a spring is directly proportional to the force applied.
b) The stretch of a spring is proportional to the number of coils.
c) The stretch of a spring is inversely proportional to the force applied.
d) Thickness of a spring wire is proportional to the force applied.
compression
the process by which the shape of a rock changes because of stress
the amount of force per square unit area on a given material
stress that occurs when an object is stretched
stress that occurs when an object is sqeezed
deformation
the process by which the shape of a rock changes.
the amount of force per square unit area on a given material
when an object starts to move to a certain direction.
tension
the process by which the shape of a rock changes because of stress
the amount of force per square unit area on a given material
stress that occurs when an object is stretched
stress that occurs when an object is squeezed
An unstretched spring becomes longer when a force is applied to it. Which word describes the additional length of the spring gains?
Expansion
Extension
Stretched
Select a logical prediction for the investigation.
As the force applied to the spring increases, the extension of the spring will decrease.
As the force applied to the spring increases, the extension of the spring will stay the same
As the force applied to the spring increases, the extension of the spring will also increase.
An elastic material can change shape when ________ is exerted on it.
a force
a moment
an acceleration
When you apply a force to an object, the object can change shape. If tension is applied, the object may be stretched. We say the object has been __________.
compressed
extended
twisted
When you apply a force to an object, the object can change shape. If a compression force is applied, the object may be squashed. We say the object has been __________.
compressed
extended
twisted
A deformation is a change in _________.
Speed
shape
direction
In the diagram, a force is used to stretch a spring. The spring is temporarily deformed when the force is applied. When the force is removed, the spring . . .
returns to its original length.
stays the same length.
The _________ of an object is the increase in its length when it is stretched.
compression
extension
The __________ of an object is the decrease in its length when it is squashed.
compression
extension
For this spring, as the force increases, the extension increases proportionally. What would you expect to happen to the extension if the force was doubled?
The extension would stay the same.
The extension would double
The extension would halve
