This is the NCERT CBSE syllabus ppt on the topic Gravitation. It will be helpful for students studying in that class and will enable them to understand better.
It is always amazing to see the interaction of planets, Sun, Stars, and other celestial objects in space which leads to astronomical events. In this chapter we will learn certain laws of physics which explains gravitation between celestial objects, free fall of body, mass and weight of the objects.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Gravitation
1. Gravitation
All objects in the universe attract
each other. This force of attraction
between objects is called gravitational
force.
2.

6.
7. Universal law of Gravitation
According to universal law of gravitation, the force
between two Objects is directly proportional to the
product of their masses.
F ∞ M X m
And the force between the two objects is inversely
proportional to the square of the distance.
F ∞ 1/d2
Combining above two Eqs…
F ∞ M X m /d2
8. Universal law of Gravitation
G Universal Gravitational Constant
( G=6.67X 10-11 N m2 kg-2 )
m1,m2 unknown masses
d2 ` Square of the distance
9. Importance of the Universal Law of Gravitation
* The force that binds us to the earth
* The motion of the moon around the earth
* The motion of planets around the sun
* The tides due to the moon and the sun.
10. Free Fall
F = G M m / d2
F = m g
m g = G M m / d2
g = G M / d2
‘d’ replaced by ‘R’
R Radius of the earth (R= 6.4X106 m)
g = G M / R2
11. To Calculate the Value of g :
G= 6.7 X 10-11 N m2 kg-2
M= 6X1024 kg
R= 6.4X106 m
g = G M / R2
= 6.7 X 10-11 N m2 kg-2 X 6X1024 kg / (6.4X106)2 m
g = 9.8 m s-2
12. Motion of Objects under the influence of
Gravitational Force of the earth :
As g is Constant near the earth, all the equations for
the uniformly accelerated motion of objects become valid
with acceleration a replaced g.
The equation of Motion are:
v= u + at
s= ut+1/2 at2
v2= u2+2as
Where u , v are the Initial & Final Velocities and s
is the distance covered in time t.
13. Mass
The mass of an object is the measure of its inertia.
The greater the mass, the greater is the inertia. It remains
the same whether the object is on the earth, the moon or
even in outer space. Thus, the mass of an object is constant
and does not change from Place to Place.
Weight
The earth attracts every object with a certain force
and this force depends on the mass(m) of the object and the
acceleration due to the gravity(g).
14. Weight
The weight of an object is the force with
which it is attracted towards the earth.
W.K.T F = ma F = mg
The Force of attraction of the earth on an object is
known as the weight of the object.
W = mg
As the weight of an object is the force with which
it is attracted towards the earth.
15. Weight of the object on the Moon
Earth
Mass M = 5.98X1024 kg
Radius R = 6.37X106 m
Moon
Mass m = 7.36X1022 kg
Radius R = 1.74 X 106 m
16. Wm = G Mm X m / Rm
2
Wm = G 7.36X1022 kg X m / (1.74X106 m)2
Wm = 2.431X 1010 G X m
Similarly,
We = G Me X m / R2
e
We = 1.474X1011 G X m
Wm/We = 0.165 ≈ 1/6
17. Weight of the object on the moon / Weight
of the object on the earth = 1/6
Weight of the object of the moon=1/6 X
Weight of the object on the earth
