Key terms
uncertainty
A measure of the doubt about the result of a measurement, often expressed as a range or percentage.
force-extension graph
A graph that plots the force applied to an elastic object against its extension, used to analyze the relationship between force and deformation.
elastic deformation
Deformation that is reversed when the force is removed.
inelastic deformation
Deformation that is not fully reversed when the force is removed.
elastic potential energy
Energy stored in a stretched or compressed elastic object.
spring constant
A measure of the stiffness of a spring, defined as the force required to extend or compress it by one unit of length.
elastic potential energy
Energy stored in a stretched or compressed elastic object.
spring constant
A measure of the stiffness of a spring, defined as the force required to extend or compress the spring by a unit length.
elastic potential energy
Energy stored in a stretched or compressed elastic object.
extension
The increase in length of an object when it is stretched.
elastic potential energy
Energy stored in a stretched or compressed elastic object.
extension
The increase in length of an object when it is stretched.
elastic potential energy
Energy stored in a stretched or compressed elastic object.
work done
Energy transferred when a force is applied to move an object over a distance.
