When velocity is changing what is happening to the slope on a position versus time graph?

That slope is the 'speed' of the motion. If the slope is changing, then the speed
is changing. That's 'accelerated' motion.
(It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated'
motion. 'Acceleration' does NOT mean 'speeding up'.)

∙ 12y agoThe slope of the position/time graph is the magnitude of velocity, i.e. speed.
It doesn't tell you anything about the direction of velocity. If the direction of
velocity is changing, the slope of the graph doesn't necessarily change.
If the magnitude of velocity (speed) changes, then the slope of the graph changes.
If speeding up, the slope of the graph increases, and the graph curves upward.
If slowing down, the slope of the graph decreases, and the graph curves downward.

If the graph's slope is changing, that means the speed is changing, and
that would be accelerated motion.

What information can be learned from a position-time graph and from a speed-time graph?
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
If you started at zero velocity, yes.

What does the slope of the line on a position versus time graph tell you about the objects speed?
The distance versus time graph shows the position of the object. The slope of the line shows the velocity of the object. The velocity is the direction and speed of an object. If your slope has a positive slant that means you are going in a positive direction. If the slope has a negative slant your object is going in a negative direction. If your slope is zero (a horizontal line) that means your object has stopped and is about to change directions. In case you didnt know a positive slant looks like this on a graph.... / a negative slant looks like this on a graph.... \ postive is like sloping up a hill negative is like falling down the hill
How do you go from a position graph to a velocity graph?
you can't....it's merely impossible! Assuming it is a graph of velocity vs time, it's not impossible, it's simple. Average velocity is total distance divided by total time. The total time is the difference between finish and start times, and the distance is the area under the graph between the graph and the time axis.
Velocity versus time?
Yes.
What is the velocity of an object at any given instant in time is known as?
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

What does the slope of a distance versus time represent?
velocity
What type of motion is occurring when the slope of a line is not zero?
Assuming the graph is for displacement versus time, the motion should be constant velocity. If velocity versus time motion is constant acceleration
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
If you started at zero velocity, yes.
How do you work out velocity acceleration?
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.
What does the slope of a velocity vs time graph show you?
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
Why is slope also called the rate of change?
For every cm you go along x, you change a certain amount in y cm. So y is changing a certain amount per unit change in x. If the plot were y versus t, then y would be called changing at a certain amount per second, like a velocity. Velocity is another word for rate of change of y.

What shape do you expect for a graph showing the position of a motorcycle versus time if the motorcycle is speeding up with a constant acceleration?
The position versus time graph is parabolic.
