Two questions: 1) If you have a horizontal force in the x direction on a pendelum supported by a wire, then it will go upwards and in the x-direction. What is the vertical component which drags it upwards? Is it the normal force which adjusts itself along the wire to match the horizontal force? 2) During the act of motion, will the speed be constant if the force isn't too big? Ie, will the normal force adjust itself in such a manner that it matches the horizontal force and gravity in magnitude?
