Motion: Physics.
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 which makes it a vector quantity while distance is regardless of direction which makes it a scalar quantity. Both distance and displacement have their S.I. unit as second (s)
TIME is that in which events are distinguishable with reference to before and after.
SPEED is distance moved by a body with respect to time. Since it deals with distance, it is also a scalar quantity and it's S.I. unit is m/s. Speed=distance/time.
VELOCITY is the displacement of a body with respect to time. It is a vector quantity and it's S.I. unit is m/s. Velocity=displacement/time.
ACCELERATION refers to the rate of change of velocity/speed. It is the increase in velocity/speed with respect to time. Acceleration= (velocity/time )/(speed/time).
I would stop here for now to continue at a later date.
Kindly drop your comments and don't hesitate to ask questions related to this topic.
Also, this week, we'll be treating Stroboscopy and Cables:computer engineering.
