Good evening, pals. We'll be discussing motion this evening. Motion, in physics refers to the change in position of a body with respect to its environment in a given period of time. Motion, as we all know, occurs everyday and is part and parcel of us. Terms used in defining motion-: distance, displacement, velocity, speed, acceleration and time. DISTANCE is the space moved by a body from one place to another regardless of direction. For instance, I could walk 5m from a point A and finally stop at a point X while another body, having started from the same point and moved the same distance could stop at a point P. Although we moved the same distance from the same starting point, our final destinations weren't the same because we went in different directions. Displacement is simply distance moved in a specific direction. For instance, "a boy walked 5m north" is not the same thing as "a boy walked 5m". Displacement always deals with a specific direction whic...
