What does elastic mean?
The object goes back to its original shape when the force is removed.
What is the opposite of elastic and what does it mean?
Inelastic The object does not go back to its original shape when the force is removed.
Which graph shows a directly proportional relationship?
A
How can both of these graphs be described?
Non-linear
How can we describe the relationship in all of these graphs?
A linear, B non- linear (inverrsely proportional), C linear, D directly proportional
What is an anomalous result in an experiment?
one that does not fit the pattern
How do we deal with an anomalous result on a graph?
circle it and then ignore it
How do we deal with an anomalous result when calculating a mean?
Don’t use it in the calculation
What is Hooke’s Law?
Force is directly proportinal to extension
Which section of the graph obeys Hooke’s Law?
The straight line section
Which section of the graph is the spring behaving elastically?
The straightline section
How will the spring be behaving in the curved section of the graph?
going inelastic
Where is the limit of proportionality?
Where the line stops being a straight line
