7 Matter Matter is any substance that has mass and takes up space by having volume. Mass is the actual amount of matter that is contained in an object. Roughly, the mass of an object is a measure of the number of atoms in it. The basic unit of measurement for mass is the kilogram. Weight is the gravitational force that is pulling on an object. Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons and ounces.

8 States of Matter Solid, Liquid and Gas, all of three are states of matter. And if we define matter, matter is any object that takes up space and has mass. Matter is made up of atoms and molecules.

10 Fluid A substance, as a liquid or gas, that is capable of flowing and that changes its shape. It can be: Liquid or Gas

11 Density is measure of how tightly matter is packed together.
The density of material varies with temperature and pressure.

12 Buoyancy A Force that act in upward direction, against the force of gravity. So it make an object feel lighter when place in fluid

13 Air is mixture of gases – tiny fast moving partials in motion.

14 Properties of air Air has a weight Air takes up space
Air presses on things Air can be compressed Air resist things moving through it Air expend when heated Air has insulating quality

15 What is Air pressure - The air that composes the atmosphere is made of many different gases. ... When gravity acts on the air, the air exerts a force upon the earth called pressure. The typical pressure at sea level is 14.7 pounds per square inch. - The 3 main factors that affect barometric (air) pressure are: Temperature of air. Altitude or Elevation. Moisture.

16 Air flow from high pressure to low pressure
Air pressure Pressure is an effect which occur when a force is applied on a surface. Pressure is amount of force acting on a unit area. Air flow from high pressure to low pressure

17 Slow Air = High Pressure
Air Pressure Fast Air = Low Pressure  Slow Air = High Pressure The 3 main factors that affect air pressure are: Temperature Altitude or Elevation or Height Moisture.

19 Balloon Rocket All rockets work by shoving gas out of their nozzles really rapidly. This pushes the rest of the rocket in the other direction, as predicted by Newton’s Third Law: “For every action there is an equal and opposite reaction.” What this means is when you push on something, it pushes back on you just as hard. - The bigger balloons move farther because they can push more air. While all of your balloons pushed air out at roughly the same speed, the bigger balloons had more “fuel,” allowing them to exert force for a longer period of time.

20 Bernoulli principal The faster air flows, the less pressure it has.
When air is moving, it creates areas of high pressure and areas of low pressure. Fast moving air creates an area of low pressure because the particles are spread further apart while high pressure air has particles packed closer together. How Bernoulli principal works principle

21 The top of the wing is curved. Air moves quickly over the wing
The top of the wing is curved. Air moves quickly over the wing. This causes Low Pressure. The bottom of the wing is straight. Air moves more slowly. This is an area of High Pressure. Higher pressure underneath pushes the wing up and produces lift. The air must reach the end of the wing at the same time so the air going over the top of the wing has a longer distance to travel so it must travel faster.

22 Bernoulli's Principle explains the shape of an airplane's wing
Bernoulli's Principle explains the shape of an airplane's wing. The bottom is flat, while the top is curved. Air travels across the top and bottom at the same time, so air travels slower on the bottom (creating more pressure) and faster on top (creating less pressure).

28 Four Forces Of flight

29 Lift To move or bring (something) upward from the ground or other support to a higher position

30 Gravity Gravity is force that attract objects together.
On earth this force attract everything to Earth

31

32

33 Drag To draw with force, effort, or difficulty; pull heavily or slowly along; haul; trail

34 Aerodynamics Designed with rounded edges so as to reduce wind drag and thereby increase fuel efficiency. Used especially of motor vehicles.

35

36 Thrust To push or drive quickly and forcibly
