gravitation
notes for this chapter
Universal law of gravitation 1]EVERY OBJECT IN THE UNIVERSE ATTRACTS EVRY OTHER OBJECT WITH A FORCE WHICH IS PROPORTIONAL OF THE PRODUCT OF THYEIR MASSES AND INVERSELY PROPORTOINAL TO THE SQUARE OF THE DISTANCE BETWEEN THEM. a b d

Importance of the universal law of gravitation
The universal law of gravitation g ravitation successfully explained several phenomena phenomena which were believed to be unconnected :
1} The force that binds us to the earth . 2}The motion of the moon around the earth. 3}The motion of planets around the sun 4} The tides due to the moon and sun.
FREE FALL
WHILE FALLING ,THARE IS NO CHANGE IN THE DIRECTION OF MOTION OF THE OBJECT S . BUT DUE TO THE EARTH·S ATTRACTION ,THERE WILL BE A CHANGE IN THE MAGNITUDE OF THE VELOCITY .ANY CHANGE IN VELOCITY INVOLVES ACCELERAION. 1}WHENVER AN OBJECT FALLS TOWARDS THE EARTH AN ACCELERATION IS INVOLVED. 2}THIS ACCELERATION IS DUE TO THE EARTH·S GRAVITATION FORCE.
MASS
1]THE MASS OF AN OBJECT IS THE MEASURE OF ITS INERTIA 2}GREATER THE MASS ;THE GREATER IS THE INERTIA. OB JECT IS CONSTANT AND 3}THE MASS OF AN OBJECT DOES NOT CHANGE FROM PLACE TO PLACE.
WEIGHT
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]. THE WEIGHT OF AN OBJECT IS THE FORCE WITH WHICH IT IS ATTRACTEDTOWARD·S THE EARTH.
PRESSURE
IN
FLUIDS
1]ALL LIQUIDS AND GASES ARE FLUIDS . A SOLID EXERTS PRESSURE ON A SURFACE DUE TO ITS WEIGHT. 2 ]FLUIDS HYAVE WEIGHT,AND THEY ALSO EXERT PRESSURE ON THE BASE AND WALLS OF THE CONTAINER IN WHICH THEY ARE ENCLOSED.
THRUST
1]THE FORCE ACTING ON AN OBJECT ON ANH OBJECT PERPENDICULAR ON THE SURFACE IS CALLED THRUST.
2
]THEREFORE THE EFFECTS OF THRUST DEPENDS ON THE AREA ON WHICH IT ACTS.
PRESSURE
1] THE EFFECTS OF THRUST ON SAND IS LARGER WHILE STANDING THAN WHILE LYING. 2 ]THE THRUST ON UNIT AREA IS CALLED PRESSURE.
]PRESSURE= THRUST
3
AREA
WEIGHT
ON THE
OF AN OBJECT MOON
WE HAVE LEARNT THAT WEIGHT OF AN OBJECT ON THE EARETH IS THE FORCE WITH WHICH THE EARTH ATTRACT·S THE OBJECT. IN THE SAME WAY,THE WEIGHT OF AN OBJECT ON THE MOON IS THE FORCE WITH WHICH THE MOON ATTRACT·S THE OBJECT. THE MASS OF THE MOON IS LESS THAN THAT OF THE EARTH. DUE TO THIS THE MOON EXERTS LESSER FORCE OF ATTRACTION ON THE OBJECT.
BUOYANCY
1] THE FORCE DUE TO THE GRAVITATIONAL ATTRACTION OF THE EARTH ACTS ON THE BOTTLE IN THE DOWNWARD DIRECTION. ]SO THE BOTTLE IS PULLED DOWNWARD BUT THE WATER EXERTS AND UPWARD FORCE ON THE BOTLLE .THUS THE BOTLLE BOTLLE IS PUSHED UPWARD. 2
RELATIVE
DENSITY
1]OBJECT HAVING DENSITY LESS THAN THAT OF THE LIQUID IN WHICH THEY ARE IMMERSED , FLOAT OF THE SURFACE OF THE LIQUID.
2
] IF THE DENSITY OF THE IS MOER THAN THE DENSITY OF THE LIQUID IN WHICH IT IS IMMERSED THEN IT SINKS IN THE LIQUID.
