About Physics

To understand the basic knowledge needed for technological advances, so that we can make out work easier and effective.

Sub-Blocks

Sub-blocks of physics are -

• Light
• Sound 
• Electricity and Magnetism
• Professions and Tools

Electricity and Magnetism - Gadget

Name :- Personal Computer

Materials used to make it:- Silicon, Aluminum, Steel, Plastic

Did you know(Facts):- 

-The First Computer Weighed More Than 27 Tons

   - About 90% of the World's Currency Only Exists on Computers.

   - The First Computer Mouse was Made of Wood.

   - The First Known Computer Programmer was a Woman.

Curiosity questions: How does the monitor display 0s and 1s as graphics

Possible answers: The 0s and 1s determine if the graphic is filled or not

Sound - Instrument

Name:-  Flute

Materials used to make it:- Bamboo

Did you know (facts):

The earliest written reference of the flute dates back to                                                                       2600-2700 BC. Some famous flautists you may not have                                                                       known about include; Halle Berry, Alanis Morrissette,                                                                       Gwen Stefani, Tina Fey, and Leonardo Da Vinci

Curiosity questions: Why does the position of the cork matter in the flute

Possible answers: The Position of the cork can change the amount of sound which can be played and at what can be sounded.

Motion - Transport

Name:- Space Shuttle

Mode of transport:- Air and space

Materials used to make it:-Titanium, silicon, High-Temperature Reusable Surface Insulation tile.

Did you know (facts):- 28,000 kilometres per hour is the maximum speed of the space shuttle 80,700 kg is the heaviest space shuttle every launched. 1 ship has made 5 trips one carrying an Indian too.

Curiosity questions: Why did the space shuttle program end?

Possible answers: The proximate cause of the end of the shuttle program was the Columbia accident in 2003.

Parts and functions of the engine in your transport:- RS-25. The RS-25 is one of the most powerful engines ever built by NASA. It could reach space within 7 minutes. This pioneered the way for more engines to come.

Type of fuel used:- Super-cold liquid oxygen and liquid hydrogen

Type of energy conversion:- Fuel to heat and work

How can you make it more efficient? 

I can make it more efficient by using the SpaceX Merlin rather than the RS-25 as it is reusable and can reach space within 5.5 minutes

Light - Lighting device

Name:- Lamp 

Materials used to make it:- Glass, Resin, Wood.

Did you know (facts):

The original purpose of a desk lamp was to act as a task light. This meant it would be used to complete tasks such as reading, writing, and even building crafts. Modern uses have shown desk lamps to be more than a task light. Many interior decorators use desk lamps without bulbs as a way to decorate their office space!

Curiosity questions:- How did the table lamp turn from a task light to a decoration?

Possible answers:

When marble, quartz and other white tiles were getting popular the steel coating of a desk lamp fitted it perfectly. According to one designer, he said “The desk lamp looks so complex, yet so simple. It was a perfect fit for rich homes. As people copied rich peoples home designs it became a decoration.

How can I make it more efficient?

I can make it more efficient by adding an energy-efficient bulb (like LEDs) and adding a battery so that if power is cut It can function still until it comes back.

Professions and Tools - Police Officer

Name:- Police Officer

List the tools used in your chosen profession and their uses:

 

Police Cap – The police cap helps the police officer with head protection and makes the officer stand out

Police Badge – The police badge is the official certification of a police officer
