Thanks that makes sense, but I'm still not quite sure on the mass providing the force, because it says that by having this mass constant, the force will remain constant, but what i that constant force going to be is the mass is 250g??
I had to do an experiment where you manipulate and change different variables (mass providing centripetal force, radius etc.) and then further invesigate the effects on centripetal force that these changes had.
My problem is that it says that by keeping the mass providing the centripetal force...
