Wave motion is the most universal physical phenomenon, we discover the wave motion all around us. Mechanical waves—acoustic wave, water wave Electromagnetic waves—radio, light wave Matter waves—electron wave

Collisions: All around us (cars, buses) Grand astronomical scale (stars, galexies) Nuclear, atomic and molecular physics The impulse-momentum theorem relates the change in the momentum of a system to the total force on it and the time interval during which this total forces acts

All around us: wheels, skaters, ballet, gymnasts, helicopter, rotors, mobile engines, CD disks, … Atomic world: electrons— “spin”, “orbit”. Universe: planets spin and orbiting the sun, galaxies spin, …

I. Choose the Correct Answer . real engine has an efficiency of33%. The engine has work output of2 4J4 per cycle.how much heat energy is extracted from the high-temperature reservoir per cycle? (D) (A)8J

1 Physics as Natural Philosophy Physics is one of the liberal arts, combining elements of reason, philosophy, mathematics, language, and rhetoric. The term natural philosophy reflects the creative and dynamic interplay that exists in physics among experiment, theory, logic, insight, inspiration, symmetry, beauty, and language

The Heisenberg uncertainty principles Nature is bilateral: particles are waves and waves are particles. The particle aspect carries with it the traditional concepts of position and momentum; The wave aspect carries with it the concepts of wavelength and frequency

26.1 Some important discoveries at the end of the 20th century a. Measured the charge of the cathode rays; b. Make a static electric deflection of the cathode rays; . Measured the charge to mass ratio of the cathode rays;

The causes of acceleration of a system--The first law of motion states that zero total force exists when the system has a constant velocity; a nonzero total force on the system causes its acceleration
