Physics Bookmark State which of the following situations are possible and give an example for each of these: (a) An object with a constant acceleration but with zero velocity. (b) An object moving in a certain direction with an acceleration in the perpendicular direction. Medium share Share Video Explanation Solution To Question ID 464649 play-icon Answer (a) Let say a stone is thrown in vertical direction with INITIAL speed u. As the time passes its velocity decreases and at the maximum HEIGHT it attained, its velocity is zero but it has an acceleration (9.8)m/s 2 in the downward direction due to gravity. (b) When a pebble is tied with an end of string and it is whirled in horizontal circular motion with the other end of the string at the centre of circular path, then it has a constant magnitude of CENTRIPETAL acceleration TOWARDS the centre. Hence the acceleration is in perpendicular direction to the motion of pebble. |
