Chapter 5
The gravitational attraction of the sun for earth is __ that of earth for the sun
The same as
On the surface of a certain planet the acceleration due to gravity F has a numerical value 5.2 m/s^2 this means that
The weight of 1 kg of a body at that location is 5.2N
On the surface of a certain planet the gravitational field strength has numerical value gplanet an object that experiences a gravitational force of 0.7 N on this planet must have a mass of
0.7/gplanet
A 320 kg satellite experiences a gravitational force of 800N what is the radius of the satellites orbit (earths radius is 6400 km)
12,800 km
A 600 kg geosynchronous satellite has a orbital radius of 6.6 earth radii what is the gravitational force does earth exert on the satellite
138N
Sally is an astronaut who has a mass of 60 kg currently she is conducting experiments in a permanent space station that is orbiting earth at a altitude equal to earths radius what is the force of gravity acting on Sally while she is in the space station
150N
What is the acceleration due to earths gravity at a distance of one earths radius above earth surface
2.5 m/s^2
Communication satellites are synchronous satellites that orbit earth each
24 hours
The gravitational force between two metal spheres in outer space is 1000N how large would this force be if each of the two spheres had twice the mass
4000N
A 90 kg satellite orbits a distant planet with a radius of 4000 km and a period of 280 min. from the radius and period you calculate the satellites acceleration to be 0.56 m/s^2 what is the gravitational force on the satellite
50.4N
Earths exerts a gravitational force of 7000N on one of the communication satellites what force does the satellite exert on earth
7000N
The acceleration due to gravity on titan Saturns largest moon is about 1.4 m/s^2 what would a 60 kg scientific instrument weight on Titan
84N
If earths mass were suddenly in magically reduced to half its present value the suns gravitational force on earth would
Be reduced by a factor of 2
Over which of the following locations is it possible to have a synchronous satellite
Equator
Does the moon orbit the sun
Yes but it also orbits earth
