Describing Motion

• In describing motion through visuals, a Point of Reference is essential to establish or identify. It is something seems steady that is used to compare the initial & final position of an object.
• Distance is the total length along a path between two points. It is a scalar quantity which is specified by magnitude or size alone.
• Displacement gives both the length and the direction of an object's path from its starting point straight to its ending point. It is a Vector quantity which is characterized by magnitude and direction.
• Motion - occurs when an object changes position over time.
• Speed is a measure of how fast or slow an object travels. It has the rate at which distance is covered over time.
• Constant Speed is attained when there is uniform change in distance in a given unit of time.
• Average Speed is the rate at which total distance traveled varies with the total time taken.
• Average Velocity is the total displacement of the moving object divided by the time it takes for that displacement, assuming that the body traveled with changing speeds and direction.
• Average Velocity is the distance traveled in a particular direction per unit time.
• Velocity refers to the speed of an object in a particular direction. It is the rate at which an object changes position in a particular direction
• Instantaneous Speed is measured at a particular time or at instant.
