Document Summary

Knots 1 nautical mile per hour. When there is a highly variable wind with a speed > 15 knots, a weather report will include the wind gust. Wind gust maximum observed wind speed. Wind direction the direction from which the wind is blowing. North wind blows from north to south. A parcel of air (blue circle) will move in the direction of the net force, which is the sum of the forces acting on the parcel. Forces are characterized by direction and magnitude (strength( Two+ forces can act not he same point or object. Net force resultant; the overall force that results from interacting forces that are expressed as a single force. 2 forces acting at an angle = resultant force is along a diagonal. Force applied to an object without other forces = acceleration. Velocity the magnitude and direction of its motion. Magnitude of motion speed of the object; the distance traveled in a given amount of time.
