Why do winds usually change direction and speed over a large body of water?

Becouse whater is smoother than earth and its friction is smaller. As the air experiments less friction it accelerates to a greater speed.Then, Coriolis force is greater as the speed increases and the wind change its direction to the left if it moves from N to S or to the right if it moves from S to N, for example. When the wind reaches the earth surface it decreases and its direction is again the initial. :)

What are the kinds of motion according to the change in direction and change in speed?
Acceleration is a change in speed or direction. Velocity is the speed and direction. ex. 41 mph northeast
How can you change the velocity of a bicycle?
At any instant change the direction of path. Consider the case you are cycling in a straight line with constant speed if you change the direction of your path but continues at constant speed then there will be change in velocity it does not depend upon your speed. Pedal faster. Well if you continues in same direction and increase your speed. Then velocity will also increase. A large number of cases exist for the asked question. I hope that helped.
Higher speeds require more space for a maneuver?
Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
A situation in which you can accelerate even though you speed does not change?
"Acceleration" means a change of speed or direction of motion, or both.If you change direction ... like turning a corner ... then there is acceleration,even though your speed is constant.Anything traveling on a circular track, even at a constant speed, has constantacceleration.

Why does a change of speed produce a change in direction?
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)

How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.

Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.

A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
Velocity is the change of speed and direction of an object?
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
What kind of motion does the speed and direction not change?
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
What makes velocity different from acceleration?
Acceleration is the change of speed upward. Velocity is any speed, in a fixed direction. So the diference, is that in speed; the direction can change, but the speed remain constant. Only if it moves faster or slower dose the speed change. So in velocity, if the speed, or the direction change, then the velocity changes.
Velocity is the change of speed and/or direction of an object?
FALSE. Acceleration is the change of speed and/or direction of an object.
