The resultant force towards the centre of a circle acting on an object moving in a circular path
2 of 12
Distance
The scalar quantity that describes the actual distance covered between two points along the path travelled
3 of 12
Ellipse
An oval. The shape of an orbit
4 of 12
Force
Any influence on an object that causes it to change direction or speed
5 of 12
Geostationary orbit
An orbit around Earth at a specific altitude such that the satellite stays above the same point on the Earth's equator
6 of 12
Gravity
The universal force that attracts any mass to every other mass in the universe
7 of 12
Orbit
The elliptical path a smaller object takes around a larger object in space
8 of 12
Polar orbit
A low altitude, high speed orbit going over the Earth's poles. A satellite in a polar orbit makes several passes around the Earth each day
9 of 12
Satellite
A smaller object orbiting around a larger object in space. Satellites may be natural, such as the Earth's moon, or artificial, such as communications satellites
