SI quantities and base units

CIE-style objective and structured questions assess the five AS-Level base quantities, derived units, dimensional checks, prefixes from pico to tera, and standard-form calculations.

Objective question 1

Which list contains only the five SI base units required in this AS-Level module?

Objective question 2

Which expression is equivalent to a newton?

Objective question 3

The pascal in SI base units is:

Objective question 4

Which equation is dimensionally homogeneous?

Objective question 5

Which prefix pair is correct?

Structured question 1

A force of 18 N moves an object 5.0 m in 3.0 s. Calculate the power transferred.

Structured question 2

Convert 7.5 pF to farads. Enter the exponent n when the answer is written as 7.5 × 10ⁿ F.

Structured question 3

Pressure p = F/A. A force of 240 N acts over 0.080 m². Calculate the pressure.
