Total Force on Wall Meter: This meter measures the total force exerted on the wall by cannon balls. You must attach the total force meter to a red hotspot on the wall (see Cannons & Wall).

Only the probe connects to the hotspot on the wall. The meter itself appears to the right. You can move the meter, but you cannot delete it. To delete the meter, you must delete the probe.

The display of this meter should roughly equal the product of the displays of the impulse per collision meter and the collisions per second meter.

You must place a total force meter to plot Total Force using the graph tool.
