hookes law Flashcards
what is hookes law?
the extension of an elastic object is directly proportional to the force applied, up to the limit of proportionality
an elastic object will…..
return to its original shape when stretched
what is elastic deformation?
an elastic object will return to its original shape when stretched
what are some examples of elastic objects that obey hookes law?
rubber/ elastic bands
what does plastic experience?
inelastic deformation- it won’t stretch it will just break
what is the limit of proportionality (elastic limit)?
force and extension are no longer proportional to eachother and the material will not return to its original shape- its permanently deformed
what is the formula for hookes law?
F= kx
what equipment is required for the hookes law practical?
clamp and stand, ruler, spring/rubber band, 5x100g masses, 100g mass hanger, pointer, tape marker, pulley, g-clamp and wooden blocks
what is the independent and dependant variable in the hookes law practical?
iv- force
dv- extension
