What is the uniform body model? - CORRECT ANSWERS Mass is distributed evenly
What is the light object model? - CORRECT ANSWERS Mass of the object is small compared to
other masses
What is the peg model? - CORRECT ANSWERS A support from which a body can be suspended
or rested
What is the gravity model? - CORRECT ANSWERS 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? - CORRECT ANSWERS 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? - CORRECT ANSWERS mass concentrated
along a line, no thickness, rigid
What are the assumptions made in the lamina model? - CORRECT ANSWERS mass is
distributed across a flat surface
What are the assumptions made in the uniform body model? - CORRECT ANSWERS mass of
the object is concentrated at a single point at the geometrical centre of the body
