# Adding a velocity or force to a part

To move a Motion part with a velocity handle:

1. Move your cursor over the part and drag on the handle that appears.
2. A vector is displayed, that lets you choose the part's initial velocity and the direction in which it will travel.
3. When you release the mouse button, the part will start moving.

You can switch the velocity handle to a force handle in the part's Properties pane. This lets you select the force to be applied by the part.
