1.Weight
force a body exerts due to the pull of gravity
2.Mass
the measure of the amount of material in a body
3.Weight=
mass x velocity
4.Objects are stable if
lower com
large surface area
5.Objects will topple if
vertical line through the com falls outside the base
a moment is produced which causes the object to rotate
6.Com is
the point where all the mass of that object may be considered to be
7.Balance at com because
the moments on each side are equal
8.Density is
mass per unit volume
9.Density=
mass/volume
10.Density tells us
how closely the particles are packed
11.Friction is
a force that opposes motion
12.Air resistance or drag
occurs when the object moves through air or fluid
, 13.Reduce friction by
lubrication
changing the material or fluid
rollers
streamlining
14.Friction acts in the
opposite direction of the object
15.Friction exists
when two surfaces move over each other
16.A force can
change the direction of motion
change the shape of things
start objects moving and slowing down
17.Two main groups
contact and distant
contact
forces touch the object and produce a change of shape or state of motion
distant
forces act at a distance
18.1st law
a body will remain at rest or move at a constant velocity if the resultant force acting on the
body is zero
19.Balanced forces exist when
two forces act in opposite directions but are the same size
20. 2nd law
if a resultant force acts on a body the body will not remain at rest or move at constant
velocity, it will accelerate
21. Resultant force=
mass x acceleration
