This presentation is an extremely amazing piece of information and it will tell you about forces and some very simple physics

1. The Forces
Today I will be teaching you the basic
Knowledge of forces and some
simple physics!

2. What are forces?
Forces are simply a push or a pull
This simply means they
are pulling in opposite
directions.
These are opposing forces.

4. Electromagnetic force affects electrically charged particles. Along with
gravity, it is the force that we see most on a daily basis. It is responsible for electricity,
magnetism, and light. Of the four fundamental forces of nature the electromagnetic force
is the second strongest and, like gravity, operates over unlimited distances.
Magnets
Unlike gravity, the electromagnetic force is felt only by objects that have an electric
charge, which can be positive or negative, differing types of charges attract one another,
but those with the same type repel.
Magnets have two poles
a south and north pole.
When the north (+) pole
meets a south (-) pole they
attract.
Since most objects, most of the time, do not have an overall electric charge, they do not
feel the electromagnetic force, so for example a child playing with two toy cars can bash
them together and they are not repelled or attracted to each other as they aren’t
electrically charged simply gravity affects them and pushes down on them so they don’t
float off.

5. What are weak nuclear
forces?
The weak nuclear force is the force
that stops the sun from burning too
fast and if this force was any stronger
the sun would have extinguished
before there was life on Earth. The
force remains hidden inside the
atomic nucleus. This is a push force.

6. The strong
nuclear force is
what is
liberated during
nuclear
reactions, of
the sort that
take place in
the Sun,
nuclear power
plants, and
nuclear bombs.

7. What is gravity?
In the very beginning of the universe, after the Big Bang, gravity pulled
atoms together to make stars and planets. Once the stars and planets had
formed, gravity kept the planets in orbit around the stars, and moons
orbiting around the planets. And on each planet that is large enough, gravity
keeps an atmosphere around the planet, like earth. The moon has no
atmosphere and very little gravity therefore an astronaut would weigh a lot
less on the moon than on earth but his mass (stuff inside him) would be the
same!
On Earth, gravity keeps the air around us (and everything else) from drifting
off into space. Gravity also causes things to fall to the ground, and causes the
ocean's tides, and causes hot air to rise while colder air falls (which in turn
causes wind).

8. Did you know?
The earth pulls the Moon
towards it. The Moon pulls
the earth towards it with
exactly the same force but in
the opposite direction.
The effects of Forces

9. Forcey facts
• Well did you know your body uses forces as well as
anything else.
• This force is used when your heart pumps blood
around your body which potentially keeps you alive.
• Without forces life would never of existed
anywhere.
• Forces are what allows us to move, forces keep us
from floating out of the earths atmosphere it’s what
makes us who we are.
