Particle - CORRECT ANSWERS Dimensions of the objects are negligible
Rod - CORRECT ANSWERS All dimensions but one are negligible, like a pole or a beam
Lamina - CORRECT ANSWERS Object with area but negligible thickness, like a sheet of paper
Uniform body - CORRECT ANSWERS Mass is distributed evenly
Light object - CORRECT ANSWERS Mass of the object is small compared to other masses, like a
string or a pulley
Inextensible string - CORRECT ANSWERS A string that does not stretch under load
Rough surface - CORRECT ANSWERS If a surface is not smooth, it is rough
Wire - CORRECT ANSWERS Rigid thin length of metal
Smooth and light pulley - CORRECT ANSWERS All pulleys you consider will be smooth and light
Bead - CORRECT ANSWERS Particle with a hole in it for threading on a wire or string
, Peg - CORRECT ANSWERS A support from which a body can be suspended or rested
Air resistance - CORRECT ANSWERS Resistance experienced as an object moves through the air
Gravity - CORRECT ANSWERS Force of attraction between all objects. Acceleration due to
gravity is denoted by g
What is assumed when modelling a particle? - CORRECT ANSWERS Mass of the object is
concentrated at a single point
Rotational forces and air resistance can be ignored
What is assumed when modelling a rod? - CORRECT ANSWERS Mass is concentrated along a
line
No thickness
Rigid (does not bend or buckle)
What is assumed when modelling a lamina? - CORRECT ANSWERS Mass is distributed across a
flat surface
What is assumed when modelling a uniform body? - CORRECT ANSWERS Mass of the object is
concentrated at a single point at the geometrical centre of the body - the centre of mass
What is assumed when modelling a light object? - CORRECT ANSWERS Treat object as having
zero mass
Tension the same at both ends of a light string
What is assumed when modelling inextensible string? - CORRECT ANSWERS Acceleration is the
same in objects connected by a taught inextensible string?
