What is the 1st set in a mathematical modelling process? -
Answer>>Setup mathematical model, assumptions and
variables
What is the 2nd step in a mathematical modelling process? -
Answer>>Solve and interpret
What is the 3rd step in a mathematical modelling process? -
Answer>>Ask is your answer reasonable?
If the answer to the 3rd step in the mathematical modelling
process is yes then what is the 4th? - Answer>>Reconsider
assumption
If the answer to the 3rd step in the mathematical modelling
process is no then what is the 4th? - Answer>>Report solution
What is the particle model? - Answer>>Dimensions of the
object are negligable
What is the rod model? - Answer>>All dimensions apart from
one are negligible, like a pole or beam
What is the lamina model? - Answer>>Object with area but
negligible thickness, like a sheet of paper
What is the uniform body model? - Answer>>Mass is distributed
evenly
, What is the light object model? - Answer>>Mass of the object is
small compared to other masses
What is the inextensible string model? - Answer>>A string that
does not stretch under load
What is the wire model? - Answer>>Rigid thin length of metal
What is the bead model? - Answer>>Particle with a hole in it for
threading on wire or string
What is the peg model? - Answer>>A support from which a
body can be suspended or rested
What is the gravity model? - Answer>>Force of attraction
between all objects. Acceleration due to gravity is denoted as
g=9.8ms-2
What are the assumptions made in the particle model? -
Answer>>mass of the object is concentrated at a single point,
rotational forced and air resistance can be ignored
What are the assumptions made in the rod model? -
Answer>>mass concentrated along a line, no thickness, rigid
What are the assumptions made in the lamina model? -
Answer>>mass is distributed across a flat surface
What are the assumptions made in the uniform body model? -
Answer>>mass of the object is concentrated at a single point at
the geometrical centre of the body
