When you have an inextensible string....

• Use different accelerations

• Use same accelerations

• This has nothing do with acceleration

• who cares?

In a light string situation....

• Tension is the not impacted

• Tension is not the same

• Tension is the same

• Force is the same

With uniform rods...

• Weight is distributed

• Mass is distributed

• Weight acts at the midpoint

• Mass of the object is at the centre

With Uniform Rods....

• Mass acts at the centre

• Mass is evenly distributed

• Mass and Weight are the same

• Newtonian Rule applies

When we have a rod...

• Thickness does matter

• Thickness does not matter

• Thickness is measure using a scale

• Ask Dr Mohammadi, he would know

A lamina...

• is a bumpy sheet

• is a thin plate

• is form of a book

• is a flat sheet

Particles have...

• Their mass concentrated evenly

• No concentration

• Their mass concentrated at a single point

• Concentration is neglected

Negligible particles..

• Are rigid

• Have no air resistance

• Have drag

• Are not rigid

A rod...

• Is rigid

• Is not rigid

• Bends easily

• Does not bend easily

In a uniform body....

• Mass is distributed evenly

• Mass of the object is concentrated at a single point

• There is a centre of mass

• There is a geometric centre
