Newton laws of dynamics. Equilibrium of a rigid body (forces and

torques) with applications: inclined plane, lever, pulley, winch; Hooke’s law; Friction forces; Motion of the center of mass of a rigid body. Harmonic motion Period, frequency, amplitude.

Momentum, force impulse, Newton’s second law as a momentum change.

Work. Power. Kinetic Energy.

Conservative forces. Gravitation potential energy, elastic potential energy. Conservation of energy and momentum. Elastic and an elastic scattering (simple scattering, scattering from a wall)
