When an object is changing its position with reference to another body, we say it is in motion. As with force, motion has a magnitude and a direction. Wind is air in motion relative to the ground. Weather reports include wind speed and direction. The average wind speed and average wind direction are usually reported.
Wind direction is reported as the direction from which the wind is blowing .
It is reported with respect to compass directions or the number of degrees east of north. A north wind blows from the north to the south . Windward refers to the direction the wind is coming from, while leeward denotes the direction the wind is blowing towards. If a body increases its speed at a constant rate, it undergoes a uniform acceleration. A free falling body is a good example of an object that undergoes uniform acceleration.
