Resource summary
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
