Average Impulse per Collision Meter: This meter measures the average momentum cannon balls impart to the wall when they collide with it. You must attach the average impulse 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 product between the displays of this meter and the collisions per second meter should approximately equal the total force.

You must place an average impulse meter to plot average impulses per collision using the graph tool.
