Forces and Elasticity

Question	Answer
A Force acting on an object may cause it to...	... change shape.
An elastic object, E.G a spring, stores...	... elastic potential energy when stretched or squashed.
When spring is stretched, what is happens?	Work done in stretching, it is stored as elastic potential energy.
When the force is removed, the elastic potential energy...	... causes it to return to its orginal shape.
The extension of an elastic object is...	... directly proportional to the force applied.
The proportionality is true until the elastic limit is reached, after that...	... the object is completly deformed.
The Formula is Know as Hooke's Law...	F = K x e F is the force in newtons (N) k is the 'spring constant' in newtons per metre, (N/m) e is the extension in metres, (m)
Different materials have...	... different spring constants.
