What is the best description of the relationship shown in this graph?
In this graph, the relationship between force and spring constant 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.
When comparing spring A to B,
A has a larger spring constant than B so A is a stiffer spring
B has a larger spring constant than A so B is a stiffer spring
What is the independent variable?
The type of rubber bands used
The weight added to the rubber bands in Newtons
The type of weights used
The extension of the rubber bands in mm
How would you measure the dependent variable?
With a weighing scale
With a ruler
With a timer
