Science 5

Day 5

1. Elevator pully

Counterweight system

Observation is very important

Need facts to prove the concept

  

2. Elevator acceleration

The elevator should be moving at a constant rate

The angular rope is longer

The Speed of the elevator is constant

Phypox only measure vertical

3. Barometer

Pressure = Force / Area (Sec 1)

= Mass x g / Area

= Density x Volume x g / Area

= Density x Area x Height x g / Area

= Density x Height x g (Sec 3)

U-tube observed in the museum

 

4. Super Computer

Assembly Language

Programme Electronics

Directly programming electronics

Transistors 

Electricity - Electronics - Assembly Language - Super Computer

5. Induction

Production of electricity

2nd Industrial Revolution

6. Pendulum
