Daemon : Gravity

This is a global daemon acting with equal strength at any point of the 3D space.

Affect

There are two options:

• "Force" accelerates the particles and they become faster and faster as long as the force is acting on them. 
• “Velocity” only works with particles and adds the daemon's "Strength" value to a particle's speed. As long as there are no other daemons or objects acting on the particles the resulting peak velocity remains constant during the simulation.
  An example: Let's assume the daemon's "Strength" is 9.8 and the emitter's "Speed" value is 2.0. Here, a particle's velocity will be roughly 11.8 m/s.

Strength

This is the dimension of the gravitational acceleration and it depends on your current location. “Strength" accepts both positive and negative values. The "Strength" parameter is also known as “g”. Here are some value for the most important celestial bodies:
