Modelling Assumptions Flashcards
1
Q
Air Resistance
A
- The friction of an object as it moves through space.
2
Q
Lamina
A
- An object with two dimensions (length & width) such as a sheet of metal.
- Its mass is evenly distributed across a flat surface.
3
Q
Rod
A
- An object with 1 dimension, such as a pole or a beam.
- Mass is distributed along a straight line.
- Rigid
4
Q
Light
A
- Its mass is very small, regarded as 0, such as a string or a pulley.
- Tension is the same at both ends of a light string.
5
Q
Smooth
A
- Assumes there is no friction between this surface and an object.
6
Q
Wire
A
- A rigid, thin length of metal, treated as one dimensional, either smooth or rough.
7
Q
Rough
A
- Takes into account friction on surfaces.
8
Q
Particle
A
- Dimensions of an object are negligible.
- Mass is concentrated at a single point.
9
Q
Uniform Body
A
- Its mass is evenly distributed.
- Its mass is concentrated at a single point.
10
Q
Inextensible
A
- Does not stretch under a load.
- Acceleration is constant in objects connected by a taut inextensible string.
