This book provides students in STEM fields with optimal support in learning the fundamentals of physics. Typical mechanics problems are explained step by step and solved using powerful software from the areas of spreadsheets, computer algebra, and technical-scientific computing. The programs used are available on both desktop computers and as apps on mobile devices such as smartphones or tablets, making them always readily accessible. The ability to work with these programs can also be highly beneficial in further studies and later in professional practice. After a compact introduction to mathematical methods and the programs used, the book covers the areas of classical mechanics along with its subfields.
