15. If the earth is squeezed to the size of the moon. What effect on the
gravity of the earth and why?
The acceleration due to gravity is inversely proportional to the square of its
1
radius (i.e.. g∝ ), keeping the mass constant. Thus, when the earth is
2
squeezed to the size of the moon, the radius will be less and the acceleration
due to gravity of the earth will be increased by 14 times.
16. The acceleration due to gravity of the moon is 1.67 m/s .
2
The acceleration due to gravity of the moon is 1.67 m/s It means a freely
2.
falling object increases its velocity with the rate of 1.67 m/s in every second
of time while falling towards the center of moon.
17. The acceleration due to gravity of the Jupiter is 25 m/s 2.
The acceleration due to gravity of the Jupiter is 25 m/s It means a freely
2.
falling object increases its velocity with the rate of 25 m/s in every second of
time while falling towards the center of Jupiter.
