Why do we measure acceleration in squared seconds as opposed to just seconds?
Speed, or velocity, is measured in distance per second; it is the rate of change of distance with time.Acceleration is the rate of change of velocity with time, or distance per second per second, which is distance per seconds squared,
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
How does pressure depend on area and force?
Pressure gradiant force is the change of pressure measured across a given distsnce, resulting ina net force moving from high to low pressure and is responsible for the initial movement of air.
Compare the changes in the weight of a ball with the changes in the balls mass as the height of the ball above earths surface increases?
Mass and Weight The gravitational force Earth exerts on an object is the weight of the object. Because weight is a force, it is measured in newtons. Weight is not the same as mass. Mass is the amount of matter an object contains, and is measured in kilograms. Even if the mass of an object doesn't change, its weight will change if its distance from Earth changes
What gives wind its energy?
From changes and or differences in temperature and pressure, ultimately, caused by regional differences in distances from the sun and a continuous change in distance from the sun as the globe spins.Wind is created as the pressure or temperature changes.
What is the change in pressure measured across a given distance called?
Pressure gradient A+LS
How is the amplitude of a longitudinal waved measured?
Amplitude of a longitudinal wave is measured as a change in pressure.
Why is acceleration measured in meters seconds squared?
Acceleration is the rate of change in velocity, that is the finishing velocity minus the starting velocity divided by the time taken for that change. Velocity is the rate of change in distance, that is the finishing distance minus the starting distance divided by the time taken for that change. Distance may be measured in metres and time in seconds. In that case velocity would be measured in metres per second. Acceleration is then measured in (metres per second) per second or metres per second2.
What is the change in a manometer with relation to a change in pressure of gas?
As the Pressure of the gas being measured increases the height of the fluid in the Manometer Tube increases. The reverse is also true. The graduations of the Manometer Tube gives you a reading of the Gas Pressure being measured.
What is pulse pressure?
Pulse pressure is the pressure that is felt when feeling the pulse. Measured in millimeters of mercury (mmHg), the pressure difference between the systolic and diastolic pressures is the pressure change to create the pulse, which is the pulse pressure.
Does the mass of an object change as the distance of gravity changes?
No, the measured weight of an object WILL change but the mass of an object will never change regardless of the gravitational force on object.

How does the temperature of the of the planet vary with the distance from the sun?
The distance varies very little so the temperature change is small, probably too small to be measured at present.
What is barometric trend?
The change in barometric pressure, air pressure, in the last three hours, measured in milibars. See the following link for the symbols that show past change: http://www.hpc.ncep.noaa.gov/images/pressure_trendNEW.gif
How does the temperature of the planet Venus vary with the distance from the sun?
The distance varies very little so the temperature change is small, probably too small to be measured at present.
What happens to pressure as altitude increased?
As altitude increases (i.e. when you get higher) pressure falls off inversely; a change near the higher reaches will not have as much of a pressure differential as the same distance change lower down.
Can anticyclone s intensity be measured?
Yes! There are two components to measuring the strenth of anticyclonic flow. One is the curvature of the system 1/R, where R is the mean radius of the pressure system. And secondly the winshear which contributes to anticyclonic rotation dV/dy, where dV= the change in wind speed over the distance dn represents the distance over which the wind speed change occurs.
