Question

which of these is an example of linear motion? a perfectly thrown bowling ball shooting a basketball phone ringing on vibrate

Explanation:

Linear motion is motion along a straight line. A perfectly thrown bowling ball moves in a straight line (assuming no external forces like friction causing deviation, in an ideal sense). Shooting a basketball follows a parabolic trajectory (due to gravity acting on it, it has both horizontal and vertical components of motion). A phone ringing on vibrate has oscillatory (back - and - forth) motion.
