Flashcards in Forces and Elasticity Deck (6):

Elastic objects store energy as [ ]

Elastic potential energy


What is an elastic object?

An object that can return to its original shape after it has been stretched/changed shape


[ ] to an elastic object to change its shape. The energy is stored as [ ]

Work is done
elastic potential energy


The elastic potential energy is then converted to [ ] when the force is removed and the object [ ]

kinetic energy
returns to its original shape


What is the equation for force applied on a string?

F = k*e
Force (N)
k = Spring constant (N/m)
e = extension (m)


There's a maximum force that the elastic object can take and still extend [ ]. This is know as the [ ]. If you increase the force past this then the material will be [ ]

limit of proportionality
permanently stretched
