Forces and Friction

What is the key assumption of the particle model in mechanics?

A

Size and shape are ignored, so all forces act through a single point.

B

Mass and weight are equal, so all forces act through the centre of mass.

C

Size and shape are ignored, so all forces act along a single line.

D

Size and shape are important, so all forces act through a single point.
