What's ratio of the orbital period for a satellite in
a geosynchronous orbit around the Earth to that of a satellite in
an orbit slightly above the surface of the Earth? The Earth has a
radius of 6371km, and a satellite in a circular geosynchronous
orbit has a radius of 42000km from the center of the earth. The
mass of the Earth is 5.792*10^24kg, and Newton's gravitation
constant is G=6.674*10^-11N*m^2/kg^2
What factors affect the speed of a satellite in circular orbit
around Earth. And, how would you calculate that speed?
A hollow hoop and a solid disk are released from rest at the top
of an incline plane that has friction. Which will reach the bottom
of the hill first and why?
What is impulse and how does it relate to the average force
applied to an object during a collision? Include one physical
example in your explanation.
why does a satellite in a circular orbit travel at a constant
speed (choose all that apply)
a. there is no force acting along the direction of motion of the
satellite
b. the only force is the force of gravity
c. there is no component of net force in the radial direction
d. the net force acting on the satellite is toward the center of
the path
e. There is a component of the net force acting in the direction...
Draw a free body diagram for a satellite in an elliptical orbit
showing why its speed increases as it approaches its parent body
and decreases as it moves away
1-Why doesn't the force of gravity change the speed of a
satellite in circular orbit?
2-A circularly moving object requires a centripetal force. What
supplies this force for satellites that orbit the Earth?
3-A 'geosynchronous' Earth satellite can remain nearly directly
overhead in Singapore, but not in San Francisco. Why?
4-True or false: For orbits of greater altitude, the period is
longer.
5- Fill in the blank:
____(a)______gathered the data that were used to show that the
planets travel in...
An Earth satellite moves in a circular orbit 924 km above
Earth's surface with a period of 103.3 min. What are
(a) the speed and (b) the
magnitude of the centripetal acceleration of the satellite?
Your task is to place your spacecraft in circular orbit about
Mars with an orbital period of 8 hours and 40 minutes. The mass of
Mars is 6.45 x 1023 kg, and the radius of Mars is 3394 km. What
will be the radius of your circular orbit?
