Is it possible to run round an oval running track at constant velocity?
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
How is velocity related to the angle of a slope?
Velocity is the slope of the position vs. time curve.
Is Average velocity the slope of the line tangent to the curve on a velocity time graph at a specific instant of time?
No, it is instantaneous acceleration.
Where is deposition dominant in a stream?
On the inner curve of a meander, where the velocity of the water is the slowest.
How do you find instantaneous velocity from position time graph?
You can't, since the slope of the graph means average velocity and the area of the graph has no meaning. The only way to find instantaneous velocity from position-time gragh is by plugging the data into the kinematic equations to get the answer. Edit: Actually you can if you take the derivative of the equation of the curve it will give you the equation of the velocity curve
What is velocity-time curve?
The graph of velocity-time is the acceleration.
Can something keep a constant velocity in a curve?
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
Is the velocity constant if a car is going around a curve?
NO,velocity changes.
Which side of the stream is shallower the inside curve or outside?
Since the outside curve has a higher velocity, it has more erosion meaning the inside curve has a slower velocity more deposition causing it to be shallower. The outside curve is deep.
Why does the shape of the free fall curve tell you about how an object moces when it is in free fall?
if its a velocity / time curve, it will show diminishing acceleration (slope of the curve) up to terminal velocity (forces balanced)

Why weak acids are not used for titrations?
This is so because titration of a weak acid with a weak base do not give a sharp change inconductivity curve. Hence it is not possible to determine the end point from the curve.
How is velocity related to the angle of a slope?
Velocity is the slope of the position vs. time curve.
What is a Bézier curve?
A Bézier curve is a parametric curve defiend by a set of control points, two of which are the ends of the curve, and the others determine its shape.
What quantity is represented by the area under a velocity-time curve?
Displacement
Why do projectiles move in a curve?
After leaving the gunbarrel, the only force preventing straight line motion is gravity, the result is (apart from firing straight up) a flight path in the form of a parobolic curve. Using the launch angle and velocity, break into horiontal and vertical velocity vectors. Horizontal velocity vector is contant horizontal velocity. Vertical velocity vector will obey newtons laws up and down Using time intervals, you can plot the curve.
What is the calibration curve for rotameter?
calibration curve helps you determine the value of a unknown substance
