Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
What two pieces of information are required to calculate average velocity?
Time and velocity
''How do calculate velocity?
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
What can you calculate from velocity time graph?
accrleration
How does a stream's gradient affect its velocity?
the difference in velocity is mostly due to the great efficiency of the large downstream channel.
How does velocity affect a stream of water?
It cuts a wider, shallow channel .
How does channel roughness influence river velocity?
These obstacles causes friction between water and rocks.This ultimately reduces the velocity of river water.The more roughness of the channel, the less the river`s velocity.
How do you calculate pressure in open channel?
You can calculate pressure based on Piezometers but without a measurement I don't know that it is possible. I would say you can calculate the pressure force by P=Z(bar)*gama(water)*Area(of the channel).
How do calculate the velocity of the boat relative to the shore?
Add the rivers velocity to the boats velocity

Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.

How does the gradient of a river affect its flow?
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
What three ways does a river erode it's channel?
The River's Velocity, Gradient, and Channel shape/roughness
Which factor does not influence stream velocity?
channel size<lies
