Author a formula with physical units sub-type
This sub-type is authored by selecting the Formula with physical units option from the Sub-type drop-down list during mathematical formula question authoring.
Examples of accepted syntax for defining the Answer field value for this sub-type are:
6 mg2*t m/ssin(x) m/s^2(3*t^2+1) km/hr
The formula with physical units sub-type Answer field:
Accepts a combination of numeric quantities, algebraic formulas, unit dimensions, and physical units.
Is recommended when the student is required to specify the physical units for their response.
Recognizes response equivalence, and only recognizes physical unit equivalents as equivalent responses if the units within the student response are recognized by Möbius (check out Author a question using recognized physical units).
Example of this sub-type
Question statement:
A particle moves along the x-axis such that its position x after t seconds (s) is t2 meters (m).
Give the expression for the particle's velocity at time t.
Answer field syntax:
2*t m/s
Example of this sub-type with an algorithm
Question statement:
A particle moves along the x-axis such that its position x after t seconds (s) is $a t2 meters (m).
Give the expression for the particle's velocity at time t.
Algorithm:
$a=2+rint(5);
$b=2*$a;
Answer field syntax:
$b*t m/s
