1. Is the acceleration due to gravity a universal
constant? Explain.
2. Is the acceleration due to gravity of objects affected by the
Earth’s rotation? Explain.
On
the moon the acceleration due to gravity is -1.6 m/s. a stone is
dropped from a cliff on the moon and his the surface of the moon 40
seconds later.
How do i find the position function of the stone?
A rocket is fired from earth towards sun. Justify that
acceleration due to gravity does not depend on mass of the rocket
moving? Is the acceleration due to gravity on rocket at a point
above earth, inversely related with square of distance of that
point from earth? Explain shortly. Using the following data, how
would you determine the point where the gravitational force on the
rocket is zero? [ Note: neglect the attractive forces of other
planets on the rocket]...
The surface pressure on Venus is 92.00 atmatm, and the
acceleration due to gravity there is 0.894 gg. In a future
exploratory mission, an upright cylindrical tank of benzene is
sealed at the top but still pressurized at 92.00 atmatm just above
the benzene. The tank has a diameter of 1.80 mm , and the benzene
column is 11.10 mm tall. Ignore any effects due to the very high
temperature on Venus.
A) What total force is exerted on the...
a) What is the acceleration due to gravity on
(i) Venus, (ii) Pluto, and (iii) the moon?
b) Three objects, carrying charges of –4.0 x 10–6 C,
–6.0 x 10–6 C and +9.0 x 10–6 C,
respectively, are placed in a line, equally spaced from left to
right by a distance of 0.50 m. Calculate the magnitude and
direction of the next force acting on each that results from the
presence of the other two.
2.) For this problem the heights are low enough that the
acceleration due to gravity can be approximated as -g.
(Note: even at low Earth orbit, such as the location of the
International Space Station, the acceleration due to gravity is not
much smaller then g. The apparent weightlessness is due to
the space station and its occupants being in free-fall.)
A rocket is launched vertically from a launchpad on the surface
of the Earth. The net acceleration (provided by...

Explain why it is necessary to include the density of and the value of the acceleration due to gravity, g, in a precise definition of a millimeter of mercury (page 196).
On a planet, the acceleration due to gravity is only 7.2
m/s2. A person living on that planet throws a football
at 10 m/s at an angle of 48 degrees to the horizontal. The person
is standing, so the ball launches from an initial height of 1.8
meters above the ground. (Ignore any air resistance here.)
What maximum height from the ground would the ball reach?
What would be the flight time before the ball gets back
to the ground?
