This PPT is created by Areebah and Nimat. We have created this PPT for our Taking Action of Unit-4. We wanted to inform you about how simple machines make our life easier and how they are used in our everyday lives.
Teaches students about work & its measurements to physics, ranging from grades 6-8 grades. Also, teaches the difference between simple and compound machines, for example, inclined planes. Finally, teaches students how work can be understood as energy & efficiency.
A simple machine is a mechanical device that changes the direction or magnitude of a force.[1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force.Usually the term refers to the six classical simple machines that were defined by Renaissance scientists
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load. The ratio of the output to the applied force is called the mechanical advantage.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

9. Make Notes!
Print a copy of the
data sheet for notes on
this presentation by
clicking the pencil
below.
10. The Inclined Plane
An inclined plane is a flat
surface that is higher on one
end. You can use this machine
to move an object to a lower
or higher place.
Inclined planes make the work
of moving things easier. You
would need less energy and
force to move objects with an
inclined plane.
12. The Screw
A screw is a simple machine that
is made from another simple
machine. It is actually an inclined
plane that winds around itself.
A screw has ridges and is not
smooth like a nail. Some screws
are used to lower and raise
things. They are also used to
hold objects together.
13. The Screw
Examples of the screw:
Jar Lids
Light Bulbs
Stools
Clamps
Jacks
Wrenches
Key Rings
Spiral Staircase
14. Lever
A lever is a board or bar that
rests on a turning point. This
turning point is called the
fulcrum.
An object that a lever moves is
called the load. The closer the
object is to the fulcrum, the
easier it is to move.
15. Lever
Examples of the lever:
A hammer is a lever
when it is used to pull a
nail out of a piece of
wood.
Bottle openers
Crow bars
16. Pulley
This simple machine is made up of a
wheel and a rope. The rope fits on
the groove of the wheel.
One part of the rope is attached to the
load. When you pull on one side of
the pulley, the wheel turns and the
load will move.
Pulleys let you move loads up, down,
or sideways. Pulleys are good for
moving objects to hard to reach
places. It also makes the work of
moving heavy loads a lot easier.
17. Pulley
Examples of where pulleys
can be used:
Flag Poles
Clothes Lines
Sailboat
Blinds
Crane
18. Wheel and Axle
You have probably seen a
wheel and axle on a car. The
axle turns when you put force
on the wheel.
The axle is a rod that goes
through the wheel. This lets
the wheel turn. It is easy to
move things from place to
place with wheels and axles.
19. Wheel and Axle
Examples of Wheels and
Axles:
Cars
Roller Skates
Wagons
Door Knobs
Gears in Watches, Clocks,
and Bicycles
20. Wedge
A wedge is a simple
machine used to push two
objects apart. A wedge is
made up of two inclined
planes. These planes meet
and form a sharp
edge. This edge can split
things apart.

74. Standard
6-5.7 Explain how the
design of simple machines
(including levers, pulleys,
and inclined planes) helps
reduce the amount of force
required to do work
76. A lever can be designed to reduce force
required to lift an object in two ways:
By ______________________ the distance
from the ____________ to the point where
the effort force is applied
By _____________________ the distance
the ____________ is from the fulcrum
77. Is it easier to lift the box of books when the
fulcrum is in the center of the board, or when the
fulcrum is at the end of the board closest to the
box?
Is it easier to lift the box of books when you
apply a force on the effort arm near the fulcrum,
or far away from the fulcrum?
Name one way you could
change this lever to reduce
the effort force required to lift
the load.
78. Final Key Point
By increasing the distance
the effort force moves
relative to the distance the
weight moves, a lever can
reduce the effort force
needed to lift an object.
