The sun or the hydrogen and helium gas, produce electro magnetic radiation.In turn, these affect, the air currents, as high or low pressure, a true random muddle!The vortex is where the high and low pressure wind converge.
Particles in the wind, pressure gradient at the site of wind generation, barriers in it, etc. are also some of the forces that will determine the direction as well as the velocity of wind
No, velocity is by definition just a rate of movement that is a scalar quantity.
Acceleration
-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity
Velocity is equal to distance divided by time.
velocity, I'm pretty sure.
velocity
no as momentum=mass x velocity if velocity = 0 then momentum=0
No, velocity is by definition just a rate of movement that is a scalar quantity.
Velocity
yes
no
Yes; there is movement and it has a direction.
Velocity is an indication of a speed, including a direction. It is a vector because that is how a vector is defined (a magnitude, including a direction).
Increased velocity results in ease of upward movement after last stride giving an ease of movement to the vaulter and therefore higher jump.
Acceleration
-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity
The term used to describe the rate of an object's movement is speed or velocity. Velocity is the same as speed but also measures direction.
