Thinkers Robert Hooke Born in the year of 1635 (Freshwater, Isle of Wight) Became the greatest experimental scientist Among many other things Hooke invented universal joint and the first prototype of respirator Son of a churchman Highly respected in the world of Biology Died in 1703 Argh... The Hooke Law states that the extension of a spring is in direct proportion with the load applied to it. This means as the

load increases,

the spring e x t e n d s . F is the force that

is exerted by the spring

on that end,

measured in N k is a constant

called the rate or

spring constant

measured in N/m x is the change

of displacement of the

spring's end

from its equilibrium

position Elastic potential

energy Potential energy stored as the

result of the stretching of

the spring. What is the value

of the constant k? The constant K depends on

the material from which it is

made of. ... It is

equal

to the

work

done

to stretch

the

spring and

the

distance

stretched which

depends

upon

the spring

they can bounce back to normal... meaning that they cannot return to their previous state.... k X F E PE = 0 PE = kx 1 ___ 2 2 Graph of Hooke's Law Hooke's Law is being obeyed Linear function Applications in
