when i jump, while I'm in the air ( no air friction), my weight would be zero, right? but the equation W=mg doesn't consider that. g and m would be constant so my weight would be the same.:frown: am i missing something?

ahh... ok. I guess I have to wait till we get to momentum to fully understand this. thanks

I'm having a hard time understanding this. If a car that has a constant acceleration hits me let's say at 10km/h then at 100km/h will it exert the same amount of force on me? F= ma mass and acceleration are constant. But this doesn't seem right, does it? Do you guys know any good website or...
