Acceleration Due to Gravity
The density of a material in SI units is . In certain units in which the unit of length is and the unit of mass is , the numerical value of density of the material is :
What is meant by the statement that acceleration due to gravity is 9.8m/s2?
A body released from a height falls freely towards earth. Another body is released one sec later. The separation between the bodies two sec after the released of the second body is (ans=24.5 m).
Why does a heavier object hit the ground first when dropped from the same height?
The value of acceleration due to gravity of earth :
(a) is the same on equator and poles
(b) is the least on poles
(c) is the least on equator
(d) increases from pole to equator
State the factors on which acceleration due to gravity (g) depends?
If the radius of the earth were to shrink by one percent, its mass remaining the same, the acceleration due to gravity on the earths surface would
At which place will the weight of an object be highest?
The atmosphere is held to the Earth due to:
Gravitational force of Sun
Rotation of Earth
Gravitational force of Earth
Gravitational force of Moon
The acceleration due to gravity is at a point distance from the center of earth . if then
Where is the acceleration due to gravity minimum and maximum on the surface of the earth?
- Mass of the body
- Mass of the earth
- Shape and size of the body
- Volume of the body
Sometimes we use 9.8 m/s2 for the value of acceleration due to gravity and sometimes we use 10 m/s2 for the value of acceleration due to gravity. What is the reason behind this?
The value of 'g' is minimum:
at poles of earth
at equator of earth
Calculate the acceleration due to gravity on the surface of Mars having a mass of and a radius of .
Determine the acceleration due to gravity at a height of from the earths surface ? Take acceleration due to gravity at earths surface to be .
The Moon's mass is ___ ×1022 kg.
Gravitational force acts on all objects in proportion to their masses, still a heavy object does not fall faster than a light object because
of the air friction
acceleration due to gravity does not depend upon the mass of an object
during falling, masses are considered negligible
because heavy object produces less acceleration due to gravity as compared to light object
- mass of body
- mass of Earth
- radius of Earth
Does the acceleration produced in a freely falling body depend on the mass of the body ?
If the earth suddenly stops rotating, then the weight of an object of mass at the equator will [ is the angular speed of the earth and is its radius ] :
An iron sphere of mass 10 kg has the same diameter as an aluminium sphere of mass is 3.5 kg. Both spheres are dropped simultaneously from a tower. When they are 10 m above the ground, they have the same
(c) potential energy
(d) kinetic energy
