In addition, the gravity can be modified in the Environment part, with the following parameters:
Gravity
Gravity scheme
The magnitude of the gravitational acceleration can be set as the standard gravity or to a user defined value.
Note that although the term gravitational acceleration is commonly used, it is more correct to talk about acceleration due to gravity. Gravity being a force, the acceleration due to gravity is the acceleration resulting from the action of gravity as described by Newton's second law.
Options:
Standard gravity (default):
The gravitational acceleration is set to the standard value of 9.80665
User defined:
The gravitational acceleration is set by you.
Gravitational acceleration (g)
Specify the magnitude of the gravitational acceleration. The gravity vector is assumed vertical.
- Default value: 9.80665
- Unit: ${\text{m}} \over {\text{s}^2}$
- Range: 0 — 1000
