Q
What is Keplers 1st law
A
The orbit of a planet is an ellipse with the Sun at one of the two foci
2
Q
What is Keplers 2nd Law
A
A line segment joining a planet to the Sun sweeps out an equal area during equal time intervals
3
Q
What is Keplers 3rd Law
A
The square of the orbital period of a planet is directly proportional to the cube of the average distance from the centre of orbit
4
Q
What is the equation for K3L and describe briefly how its derived in words
A
T² = (4π²/GM)r³
Derived by equating centripetal to gravitational force
5
Q
What is a satellite
A
An object that orbits another
6
Q
What are the two types of satellites and give examples of each
A
Natural: Moon
Artificial: ISS
7
Q
What is a geostationary satellite
A
A satellite with
- orbital period of one day
- travels in the same direction as the rotation of the earth,along the equatorial plane
- Used for communications and surveying as they provide continuous coverage
