Relationship between force and extension
The force applied to an object is directly proportional to the extension, as long as the limit of proportionality is not exceeded.
what is meant by an Inelastic (plastic) deformation
-Deformation that causes the object to be permanently stretched -object does not return to its original shape after the force is removed.
state the equation relating force, spring constant and extension. appropriate units
Force= Spring Constant x extension Force (N), Spring Constant (N/m), Extension (m)
Energy stored in a stretched spring
elastic potential energy.
What can extension be replaced with in the equation for spring force?
'compression'
