Applies a force to a rigidbody that simulates explosion effects. Other rigidbodies will be affected by the explosion within its radius - the closer they are to the explosionPosition, the stronger the force will be exerted on them.
local obj = Space.Host.ExecutingObject;

-- Place other rigidbodies around it to observe the effect!

-- Now the rigidbody is under a continuous force directed upwards (Y direction)
Adds a force to the Rigidbody at a given position (should be within the range of the rigidbody for a realistic result). Thus, both a torque and force are applied to the object.

The maximum depenetration velocity of the rigidbody (1.00000003318135E+32 by default). Can be useful to make colliding objects bounce away in a smoother fashion.

Density
float Densityset
The density of the object (1 by default). Changing this value will affect the mass of the object (the volume will remain unchanged).

-- prints "4" to the console - the density is 2 times lower, and the object is 8 times bigger, therefore it's 4 times heavier.
The diagonal inertia tensor of mass relative to the center of mass. It is defined in x,y,z axis. It is calculate by physics automatically,and if you set value to it, it would override the value.
