speed+velocity

=Speed and Velocity= By: Phoebe Morrison


 * //Speed://**

Speed is the rate of change in distance.



Or "Speed equals distance divided by time".
 * Fact -** The formula for speed is: S = d / t

Example:

The 'Mach 5' is being tested before a race, the race track used is 1000m long, the 'Mach 5' finishes one full lap around this track in 20s. m = meters and s = seconds So were going to divide 1000m by 20s. 1000/20 = 50 m/s The speed of the 'Mach 5' in this example is 50.
 * Fact -** In our formula it says to divide the distance (meters) by the time (seconds).


 * //Velocity://**

Velocity is the rate of position.



For the sake of my sanity, lets skip looking her up and call her 'Vel'


 * Fact -** The formula for velocity is the formula for speed ( S = d / s ) but with a direction stated in the answer.

Example:

Vel is running to a crime scene, the crime scene is 1000m South. She makes it to the scene in 2 minutes. 2 minutes are equivelant to 120s.

So, 1000/120 equals the velocity of Vel as she runs to the crime scene. 1000/120 = 8.5 m/s Which rounds to -9 m/s South.-


 * Fact -** m/s is the units you record velocity and speed with.
