To measure distance:

1. If you have the GPS coordinates of two locations in UTMs, you can use the following formula to calculate the distance between the two points (x₁, y₁) and (x₂, y₂):

2. In Google Earth, use the measuring icon on the toolbar (shown below), or go to the Tools menu and click on Ruler.  

To calculate area:

To calculate the area of a polygon in Google Earth, and you do not have Google Earth Pro, you can use the following website: http://www.earthpoint.us/Shapes.aspx  

Physics:

Velocity= meters/second, miles/hour Acceleration is change in speed over time; (meters/second)/second; meters/second² Force = mass X acceleration Watts=Joules/second
