which scientist are related to gravitation ?
Newton
je purkinje
Galileo
Haeckel
The force that keeps the body in a circular path and is acting towards the center is called?
Central force
Frictional Force
Centripetal Force
The motion of the moon around the the earth is due to which force ?
Gravitational force
Frictional force
Centripetal force
Option 1 and 3
Choose the correct definition of Universal law of gravitation
Every object in the universe attracts every other object with a force which is proportional to the product of the distance between them and inversely proportional to their masses
Every object in the Universe attracts every other object with a force which is inversely proportional to the square of the distance between them and proportional to the product of their masses
Every object in the universe attracts every other object with a force which is proportional to their masses and inversely proportional to the square of distance between them
What is G
Gravitation
Acceleration due to gravity
Constant of Proportionality
The value of G is :
9.8m/s-2
6.673 * 11-11
6.683 * 10 -11
6.673 * 10-11
which scientist found the value of G?
Newton
Albert Einstein
Henry Cavendish
The SI unit of G is ?
Nm1Kg1
Mm2 Kg2
Nm2kg2
The universal Law of Gravitation explained
the tides due to moon and the sun
the force that binds us to the earth
the motion of the planets around the sun
All of the above
What is g ?
Acceleration
gravitation constant
Acceleration due to gravity
what is the value of g ?
8.9 m/s-2
9.3 m/s-2
9.8 m/s-2
8.66 m/s-11
The correct equation to show relation between G and g is :
g=Mm/d2
G=Mm/R2
g=G Mm/d2
g= Gm/R2
Which off the following statement is correct about acceleration due to gravity
Value of g varies from place to place
g is more at equator than at pole
g is equal at equator and pole
g is less at the equator than at the pole
which is a correct statement about mass ?
Mass can be zero
mass is vector quantity
mass is constant everywhere
mass is derived quantity
Which among the following is a wrong differentiation between mass and weight ?
Mass is amount of matter in a body whereas weight is the measure of force acting on body
Si unit of mass is kg whereas SI unit of weight is newton
mass has both magnitude and direction whereas weight has only direction
mass can easily be measured by beam balance whereas weight can be measured by spring balance
weight of an object is directly proportional to mass
true
false
if mass is less gravitation will be
more
constant
equal
less
weight of an object on moon = ?
1/6 * its mass on earth
1/6 * twice its weight on earth
1/6 * its weight on earth
Why do we weight less on moon as compared to earth ?
because moons gravitational force is less
because moon weight less
because moon has less mass compared to earth
because is space our weight is reduced
