Circular Motion Definitions

HideShow resource information
Centripetal Acceleration
The acceleration toward the center of the circle that keeps the object in an elliptical orbit
1 of 7
Centripetal Force
The net force acting on an object moving in a circle- is always directed towards the center of the circle
2 of 7
Gravitational Field Strength
Gravitational Force per unit mass
3 of 7
Newton's Law of Gravitation
Any two point masses attract each other with force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them
4 of 7
Period
Time taken for an object to complete one orbit
5 of 7
Kepler's 3rd Law
The square of the period of a planet is directly proportional to the cube of its distance from the sun
6 of 7
Geostationary Orbit
The orbit of an artificial satellite which had a perios equal to 1 day and stays in the same point above the earth's equator
