Scientists study velocity to predict where things such as hurricanes, tornadoes, etc. are traveling and how fast they move. The definition of velocity is the speed of an object in any given direction. When both the speed and direction of an object are known you can determine the velocity of the object. All for airborne objects depend highly on velocity. Depending on if the velocity of an object is right or not could mean life or death for airborne vehicles (Jones).

Calculating Speed

In order to calculate speed you have to know the distance an object traveled and how long it takes for the object to get there. In order to find speed you need to divide distance by time. There are two kinds of speed classifications average speed and instantaneous speed. Average speed is the constant speed of an object. To get the average speed of an object you must first know the total time and distance the object traveled, and then divided them. Instantaneous speed is the rate an object moves at a given instant in time (Jones).

Describing Motion

An object is in motion if it changes position relative to a reference point. A reference point is a place or object used for comparison to determine if something is in motion. All scientists measure distance using the International system of units (the most scientific form of measurements). A meter is the basic measurement for distance in the International System of Units (Jones). Motion can occur when an object is acted on by a certain amount of force. An Object will continue to move until it is acted upon by another force with equal strength. The heaver an object is the harder it is to move, also more friction will occur making the object slow down faster.

Graphing Motion

you can show the motion of an object on a line graph in which you plot distance versus time. In a distance versus time graph time is shown on the x-axis, distance is shown on the y-axis, and the points on the graph are the total distance traveled. All the points on a distance versus time graph are connected by on line; the steepness of the line is called the slope. The slope tells you how fast one variable changes in relation to the other variable in the graph. In order to get the slope in a graph is too divided by the rise of the line by its run (Jones).
