Hand shaking because of inertia (1st Law).

Explanation:

We shake our hands to get rid of the drops. Newton's 1st Law tells us that every object will continue its state of rest or movement until a force is applied. This property is called inertia. When we shake our hand we impart a velocity to the drops, and then we suddenly change the direction our hands are moving, while the drops continue on their previous trajectory, leaving our hands. If we do it slowly it won't work because other forces would have plenty of time to act and keep the drops in our hands.

Answer from: Quest

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

Answer from: Quest

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
