Phisics

- Momentum and Torque

- Resistor, Capacitor and Inductor

- Newton Law vs Einstein's

a) Newton law of speed apply for low speed.

b) Also Einstein law apply for high speed (relativity): E=mc2

c) Same for law of gravity.

d) Einstein draw a bigger circle to Newton laws Gravity and Speed apply for law mass object and speed.

 - How electricity works - The working principle

a) the basic structure is the atom

b) the atom has nucleolus and electrons

c) electrons have negative charge and orbit around nucleolus.

d) the nucleolus have protons with positive charge and neutrons.

e) nucleolus is much heavier than electrons.
