An object is stretched by a force, but returns to its original shape when the force is removed. This type of deformation is called ___ deformation.
An object is stretched by a force and will not return to its original shape when the force is removed. This type of deformation is called ___ deformation.
Which of the following describes the extension of a spring?
Which of the following describes a variable in an experiment?

Which of the following statements about the spring constant is correct?
The following graphs show extension against applied force for three different springs. The scales are the same on all of the graphs. Which graph represents the spring with the lowest spring constant?
For elastic deformation, extension (or compression) is directly proportional to the force applied. What is the name of this law, and how is it expressed as an equation?
Cars have stiff suspension springs to ensure a smoother ride. If the spring constant of one of these springs is 60 000 N/m, the force needed to compress the spring by 2.0 cm is ___ N.
A spring has an unstretched length of 0.6 m. When a force of 200 N is applied, it stretches to a length of 1.0 m. What is the spring constant of the spring?
