what is gravitational force of earth
what is the gravitational force of earth responsible for?
why can we observe the gravitational force between the earth and a stone but not between two stones?
what is the universal law of gravitation state? derive the formula and SI UNIT
under which condition F=G?
What is centripetal force and for what do we need it for?
according to the third law, every action has an equal and opposite reaction so why do we not see the earth moving towards the stone due to the gravitational force?
what is free fall?
define acceleration due to gravity
what is the cause of the variation in the value g? why is the value of g descreased if we taken from the poles?
The atmosphere is held to the Earth by
(a) gravity
(b) wind
(c) clouds
(d) Earth’s magnetic field
Name the force that causes acceleration of an object moving along a circle and keeps the body moving.
centripetal force
centrifugal force
repulsive force
attractive force
The value of acceleration due to gravity
(a) is same on equator and poles
(b) is least on poles
(c) is least on equator
(d) increases from pole to equator
The value of g also....... we go inside the earth.
Same
Changes
Mass is a .........quantity.
Vector
Scalar
The value of Universal Gravitational constant is
6.673X10-11 Nm-2kg2
6.673X10-11 Nm2kg2
6.673X10-11 Nm2 kg-2
6.673 x10-11 N m-2 kg-2
Force of gravity is directly proportional to
Product of Mass
Weight
Distance
Time
the value of of g is about ------- the value of g on the earth
diffrentiate between mass vs weight
diffrentiate between mass vs weight
diffrentiate between g AND G
