1 (a) State the dimensions of the following quantities.
• Force
• Velocity
• Density [3]
A student investigating the drag force F experienced by an object moving through air conjectures
the formula
F ku m

= ^t h ,
where
• k is a dimensionless constant
• u is the air velocity relative to the moving object
• t is the air density
• m is the mass of the object.
(b) Show that the student’s formula is dimensionally consistent. [2]
The student carries out experiments in an airflow tunnel. When the air density is doubled, the drag
force is found to double as well, with all other conditions remaining the same.
