The subject is inteded for students who need more detailed practising and improvement (including knowledge from former physics coursess, or high-school knowledge) necessary for successful finishing Physics I course.The instructions are analogical to seminars with a short corresponding theoretical background. The link between physical concepts and methods of solution of typical problems is underlying.
1. Physical quantities - vectors and scalars. Kinematics of a particle motion in one dimension.
2. Motion in two or three dimensions, circular motion. Newton's laws of motion. Galileian transformation.
3. Motion equations, applications. Dynamics of a circular motion. Work and energy. Principle of conservation of energy. Momentum, impulse, collisions. Centre of mass. Rigid body. Rotational and translational motions, the torque. Conservation of momentum and angular momentum.
