(iii) if a body is projected vertically upwards with certain velocity then it returns to the same point of projection with the same velocity in the opposite direction. There is nothing like absolute motion. LysosomesLysosomes [Suicide bags] (Cleanliness of cell): Lysosomes are a kind of waste dispatch and disposal system of the cell. unit of speed or average speed is m/sec. The distance traveled is different for different path between A and B. Here are the PowerPoint Presentations & a few Flash files available for most of the chapters: Chapter 1 - Motion. Rest:An object is said to be at rest if it does not change its position w.r.t. (v) For an object is uniform motion no force is required to maintain its motion. time, then the motion of object is called 3-D.

If a body travels in such a way that it comes back to its starting position, then the displacement is zero. Eg :A car moving on a circular road with constant speed. Motion means movement. Earth can be regarded as a point object for studying its motion around the sun. The centrosome directs the movements of the chromosomes when a cell divides, and the centrioles help create the spindle of threads along which the duplicated chromosomes separate into the two new cells. Where are proteins synthesized inside the cell?Answer- The proteins are synthesized in the RibosomeLysosomes are known as suicidal bags of the cell? Suppose the distance between the stations is S. Time taken in reaching from one station to another station. When an object moves along a straight line and in the same direction its total path length is equal to the magnitude of its displacement.
