P8-Nuclear Physics

Rutherford Scattering The discovery of the nucleus: Before 1913 scientist believed an atom was like a plum pudding, a positive mass with electrons dotted around inside. It wasn't until Ernest Rutherford did his experiment to prove otherwise. Rutherford detected a...

P7-Fields and their Consequences

Fields Force field- a region in which body experiences a non-constant force. A field is a physical quantity that describe a conduction in the space. The conduction or value could be scalar or vector. For each point in space, field is described by field strength -...

P5-Electricity

Basics of electricity Metals are conductors, as they have delocalized electrons. when these electrons are given energy, they are free to move and act as charge carriers. conduction electrons are attracted toward the positive terminal and repel the negative terminal,...

P6-Further Mechanics and Thermal Physics

  Circular Motion                    To cause an object to move with uniform circular motion a centripetal force is required. In uniform circular motion, the object has a constant speed (here the speed is scalar and the magnitude is constant, velocity as the...

P3- waves

Wave is a vibration through a substance. λ=Wavelength – length of one whole wave cycle A=Amplitude – max magnitude of displacement from equilibrium. F=Frequency – number of cycles per second passing through a point T=Time period – the time per one complete wave to...
