Particles falling slowly

I have a scene where particles burst from their emitter at a certain time. that works fine, however as they are falling they fall incredibly slow. there are no parameters on them except for the original newtonian physics which i havent changed. in projects before they fall relatively quickly, but now they are almost floating through the air is there a way to fix this or increase the speed of the particles through the air?

Check to see if the Gravity setting is checked or not under Scene buttons.
