Experiment to see how adding masses to a spring causes it to
stretch
Set up
apparatus
as shown in diagram
Measure
mass
of each mass and calculate
weight
(force applied)
Do a
pilot
experiment first to check masses are good size
Measure
natural length
of spring
Add mass, allow to rest, measure
new length
, calculate
extension
Repeat until enough measurements (at least
6
)
Plot
force-extension
graph
View source
If the
line
of best fit is a straight
line
, there is a linear relationship between force and extension (they're directly proportional)
View source
When the line begins to bend, the relationship is now
non-linear
between
force
and extension - the spring stretches more for each unit increase in force
View source
Spring constant
Gradient of the
straight line
on the
force-extension
graph
View source
Elastic potential energy
Energy stored
in a
stretched spring
, equal to 1/2 * spring constant * extension^2
View source
Moment of a force
The
turning
effect of a force, given by force *
perpendicular
distance from pivot to line of action of force
View source
If the total anticlockwise moment
equals
the total clockwise moment about a pivot, the object is
balanced
and won't turn
View source
Levers
Increase the
distance
from the
pivot
at which force is applied, so less force is needed to get the same moment
Make it
easier
to do work, move a load or turn a
nut
View source
Gears
Circular discs
with teeth that interlock
Turning one causes another to turn, in the
opposite
direction
Transmit the
rotational
effect of a force from one place to another
Different sized
gears
can be used to change the
moment
of the force
View source
A force transmitted to a
larger
gear will cause a bigger moment, as the
distance
to the pivot is greater
