Vector3.up does not add enough force to left the base and fly into the sky

[Jadder_Moya]

Hi Rick,

The function Vector3.up or (0,1,0) does not add enough force to even move the rocket to let the base. If I add (0,2,0) its get enough force and its fly. The question is why it is not flying with Vector3.up ?

note:

• The rocket has the same transform values for position, rotation and scale, the relative mass as the tutorial.
• Rocket gameobject it is not selected in the hierarchy.
• I clicked the game Windows for focus.

please check images below.

Thanks,

Take a look at all of the overrides for Rigidbody.AddForce(). You can choose a ForceMode which will significantly alter the behavior. Vector3.Up is a normalized vector so it can be modified by a float value. In other words, Vector3.Up can be multiplied by a float value to increase the value of Y. Vector3.Up * 2.0f is the same as new Vector3(0.0f, 2.0f, 0.0f).
