Document Summary
For objects near the surface of the earth. vf s = vis + as t sf = si + vis t + v2 f s = v2 is + 2as s. For motion under the in uence of only gravity: uniform motion in the horizontal direction with vx = v0 cos , constant acceleration in the vertical direction with ay = g, same t for both motions. The friction force is parallel to the surface: static friction: acts as needed to prevent mo- tion. Can have any magnitude up to fs max = sn: kinetic friction: opposes motion with fk = Kn: rolling friction: opposes motion with fr = The force exerted by an ideal spring is: the tangential velocity is v = r, the centripetal acceleration is a = v2/r = 2r. For motion with constant angular acceleration : the tangential acceleration is at = r, the radial acceleration is ar = v2/r = 2r.
