2. Springs
Require a force to stretch or compress
them.
The force needed is related to the spring
itself.
Just like the force of friction is related to
the material used.
3. Hooke’s Law
Hooke's Law gives
the relationship
between the force
applied to an
unstretched spring
and the amount the
spring is stretched.
4. Hooke’s Law
Hooke's Law states:- the
extension is proportional to the
force
the spring will go back to its
original length when the force is
removed
so long as we don't exceed the
elastic limit.
5. F= -kx
F = restoring force of
spring
x = the distance that
the spring has been
stretch or
compressed from
equilibrium
k = the spring
constant
(-) = force acts in
opposite direction of
the displacement
6. The slope of the graph of Hooke’s Law
to determine the spring constant.
Slope = rise/run
Slope = N/m
7. The area under the force vs position graph
will give the potential energy stored in the
spring.
Area of a triangle = ½ base*height
EP = ½ kx2
