normal contact Force
Non-contact Forces
Gravitational Force
Weight is the actually a force
Weight - is the force which is caused by the mass on an object in a gravitation field.
Measured in newtonmeter
Mass measured in mass balance
Mass and weight Test
Link Title
On Earth this is 9.8 N/Kg
On the moon it is about 1.6N/Kg
2 snickers bar is about 1N of force
100g is 1N
Electrostatic
Magnetic
Force atributes
Measured in Newton (N)
Vector quantity - has Magnitude and direction
Is represented by an arrow - which give a direction as well as magnitude
:
Resultant force -
WORK
if an object is moving then it is doing some work
Force appliced x distance that object travelled
Force measured in N
Displacement in metres
Work in Joule
One Joule of work is done when a force of one Newoton causes a displacement of one metre
Define as a push or pull
Momentum
Vector or Scalar?
Momentum is a vector quantity, it has both magnitude and direction
Unit?
Kgm/s
The equation?
moment is mass x velocity
Momentum is conserved - what do
es it mean?
momentum before = momentum after
What is the relationship between force and moment?
F= change in moment / time
Energy
KE Energ of motion - KE = 1/5mv squared
PE - Energy of position
