Learning outcomes of the course unit
Instruct students in the use of the scientific method;
Have them become familiar with units of measure and orders of magnitude;
Make students capable of independently solving simple problems in well-defined contexts;
Providea general foundation in physics, emphasising comprehension rather thanrote memory and emphasising a number of basic concepts that could beuseful to the student in future studies.
It is strongly recommended that students have taken and passed the first year, first semester Mathematics and Statistics course
