Introducing
Forces
- Force
diagram
- uses
labelled
arrows
- direction
of the
arrow
- shows the
direction
of the
force
- length
of the
arrow
- is
proportional
to the
magnitude of
the force
- Resultant
of forces
- sum effect of
more than
one force
- forces in
the same
direction
adds
- forces in
opposite
direction
substracts
- if resultant
force is not
zero
- object will
be rotating
around an
axis
- object
will
be
accelerating
- Balanced
and
unbalanced
forces
- pair of forces
equal in
magnitude &
opposite in
direction
- force and
its
reaction
- When one object
exerts a force on
another object, then
the second object
exerts an equal and
opposite reaction
force on the first.
- equilibrium
- all forces
acting on an
object are
balanced
- an object at
equilibrium
will be
- moving at
constant
speed along a
straight line
- at rest
- Turning
effect of a
force
- formula
for
claculation
- changing
moment
- change
magnitude
of the
force
- change
distance
from the
pivot
