Frontal teaching, exercises. Attendance to the course is recommended.

All class schedules are posted on the EasyAcademy portal.

Written exam plus oral examination

The oral examination will verify the acquisition of theoretical knowledge.

The written exam will assess the capability of the students to apply the knowledge acquired to sol the problem of the dynamics of point masses and rigid bodies.
