Good design gets out of the way of the content you are sharing. It helps your audience focus on the content itself instead of the design.
But, it's no secret that most people dislike giving presentations. The dread of public speaking consistently ranks among the greatest fears in public surveys.
This presentation slides can help you reduce the anxiety involved with giving a presentation. Well-designed slides not only build your own confidence, they make your key points clearer to the audience.

Universe and the Solar System (Lesson 1).pptxJoenelRubino3
SHS Earth and Life Grade 11 Lesson 1. This lesson discusses the compos of the universe, the origin of the universe, different hypotheses of the origin of the universe
Studying the origins of the Universe and exploring it helps us build our civilization. Exploring how our civilization came into existence has evolved our ability of thinking and understanding our surrounding and also the universe in a better way. Our curiosity to get the answer to every query in relation to the origin and existence of universe has helped us to discover and build better technology that we so ungratefully enjoy in all walks of life. Humans have managed to advance in every field of technology, medicines, energy and telecommunication.
3. 13.7 to 15 thousand million years ago…
All the matter in the universe was compressed in a
small point.
As it started rotating, it exploded and liberated all
the energy in theUniverse.
The galaxies were formed a thousand million
years later.
This explosion of matter and energy is known
as the…
7. Forms of theGalaxies
3 types of them:
Spirals
Form of disc,

and havetheshape of anellipse.
9. Solar System
It was formed 4600 million years ago in
a cloud of hellium and rocks.
It has 2 type of planets:
Interiors
Mercury, Venus, Earth and Mars.
TheclosestonestotheSun, thefirstonestobeformed, made of
rock.
Exteriors
Jupiter, Saturn, Uranus and Neptune.

Parts of ice and rock
They travel around the Sun

18. Kepler’sSecondLaw
An imaginar line from the Sun to a
planet sweeps out equal areas in
equal time intervals whether the
planet is close to or far from the Sun.

20. Isaac Newton
Deduced that a planet is kept in orbit by the
centripetal force by the force of attraction of
the Sun.
This phenomenom is Universal
Between 2 objects of any material
Itgaveoriginto:
Law of Universal Gravitation
21. Law of Universal Gravitation
Any 2 bodies attract with a force proportional
to the product of their masses and inverserly
proportional to the square of the distance
betweenthem.

23. Albert Einstein
General Theory of Relativity
Gravity is not a force, but an effect of space itself.
It is an apparent force, and mass causes space to be
curved, and other bodies are accelerated because they
move in this curved space.
A verylargemass causes:
Distortion in space
