A vertical line on a velocity vs time graph is physically impossible.
The one that's perfectly vertical (parallel to the y-axis).
It is called instantaneous velocity and is the slope of the line tangent to the point on the position versus time graph. It also can be found by differentiating position with respect to time (i.e. dx/dt)Instantaneous Speed
The rate of acceleration is a measure of the change of the velocity of an object with time. On a graph of velocity versus time, it is represented by the slope of the line so graphed. If velocity is changing in time, the object described is being accelerated. The greater the slope of the graph, the greater the change of velocity per unit of time and the greater the acceleration of that object. true
v2 = v02 + 2a(delta x)v = sqrt(v02 + 2a(delta x))This is based on the assumption that there is constant acceleration.Another way to find velocity is using a little Calculus, this method is better since it does not assume constant acceleration, therefore this would work even if there is a change in acceleration.Since v = dx/dt, you can differentiate position with respects to time to find instantaneous velocity, given that you do know the time.And dv/dt = a, therefore dv = a x dt, integrate both sides you get velocity. This approach again requires the knowledge of time.
For comparing the acceleration of automobiles, a velocity vs. time graph is most efficient, where time is the x value, and velocity the y value. The greater the acceleration of the automobile, the steeper the slope of its respective plotted line.
vertical line because it is impossible for time to stay at 1 point and v keeps raising
The one that's perfectly vertical (parallel to the y-axis).
A verticle line is impossible. You cannot have different positions at one moment in time.
a verticla line
instantaneous magnitude of velocity
Tangent of the slope at any point = velocity
Yes.
velocity
Assuming the graph is for displacement versus time, the motion should be constant velocity. If velocity versus time motion is constant acceleration
If you started at zero velocity, yes.
