Exerting a Force

BHS -> Staff -> Mr. Stanbrough ->IP How-To Notes -> this page

Creating a Force:

To apply a force to an object in Interactive Physics:

• Select the Force tool () from the tool bar.
• Click the mouse at the location where you want the force applied. This is probably the center of mass of an object.
• Drag the mouse away from the application force in the direction opposite the direction that you want the force to act.
• Release the mouse.

Adjusting a Force:

For coarse adjustments, you can drag the force with the mouse to adjust its magnitude and direction. For fine adjustments, use the Properties Window. Here, you can type the force's x- and y-components (Fx, Fy) if "Cartesian" is selected, or the force's magnitude and direction (|F|, ) if "Polar" is checked.
