Universal gravitation
This applet simulates the motion of a celestial body under the gravitational attraction of another (much bigger) depitched as a large Yellow dot (imagine the Sun) and aproximatively motionless. As a first approximation the motion is considered as uniformly accelerated during a time interval : this is accurate only in the limit where , i.e. when the time interval is sufficiently small.
You can set
- the initial position of the moving body,
- the initial velocity of the moving body,
- the time interval .
