stretching forces Flashcards
(8 cards)
1
Q
extension
A
length - origional length
2
Q
paralax error
A
the apparent shift in an object’s position as it is viewed from different angles
be at eye level
3
Q
W
A
mg
4
Q
100g to N
A
1N
5
Q
hookes law
A
force is proportional to extension produces
force doubled = extension doubled
6
Q
practicle
A
investigate how a spring + rubber band behave when subject to tensile forces
7
Q
graph for spring
A
straught - elastic behavior - obeys hookes law
before starts to curve - elastic limit - max force for which spring would return to origional length if load removed
curve - plastic behavior - permanently deformed
end - breaking point
8
Q
rubber band graph
A
doesnt obey hookes law - not straight
but is elastic - returns to origional legth when load removed
