Models in Physics

Aim

To develop the ability to use, estimate and create models of physical systems related to classical mechanics. After successful examination the student should be able to model and analytically or numerically solve basic mechanics problems using motion equations, force laws, and derived momentum equations and energy principles. Furthermore, the student should individually and in group be able to apply experimental problem solving to handle problems related to mechanics. From the base group work, the student should be able to:

• independently and in groups, identify learning needs in relation to given problems related to the term's courses
• collaborate with colleagues in both learning and problem solving, as well as lead technical problem solving situations linked to the term's areas
• contribute to discussion and results in a base group
