In a position vs time graph what does it mean if the position is a negative number?
If acceleration is negative the graph looks like a upside U and decreases in value as time continues If acceleration is constant the graph is a straight line (linear) at 0 or whatever the velocity is
What does the slope of a speed vs time graph indicate about an object's motion?
The slope of the speed/time graph is the magnitude (size) of the object's acceleration.
What does the slope of a line on a distance-versus-time graph show?
It shows the speed of an object in a direction towards or away from the reference point. This is not the speed of the object because any motion in a transverse direction is ignored. For example, even if a racing car is going at top speed around the reference point on a circular track, the distance v time graph will be a horizontal line. The slope will be zero.
What does it mean if a line is flat on a distance-time graph?
Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
Graphs of uniform velocity?
Yes, there are velocity graphs, (velocity being on the y axis and time being on the x axis). However, these graphs are not to be mixed up with position verses time graphs. On a velocity verses time graph, (the units for velocity being m/s), an object at rest is plotted as a straight line along the horizontal axis. This shows that time is progressing, but there is no motion of the objest. Uniform motion is also plotted as a straight line, but must be placed someplace above the horizontal axis. Acceleration and decceleration on a velocity vs time graph are represented by diagonal lines unlike the curved lines on a position verses time graph
What does a slope of a time graph represent?
The slope of a velocity-time graph represents acceleration.
Is acceleration the slope of the velocitys vs the time graph?
Yes, acceleration is the slope of a velocity versus time graph.
Why does the slope of a velocity time graph give you acceleration?
if there is a slope, the velocity is either increasing or decreasing. This is acceleration.
How do you make a velocity vs time graph from an acceleration vs time graph?
Your acceleration vs. Time graph is the slope of your velocity vs. time graph
Velocity is the slope of the displacement vs time graph?
Velocity is NOT the slope of the acceleration vs. time graph. Velocity is the area under the acceleration vs. time graph. Velocity is the slope of a position vs. time graph, though. For you Calculus Junkies, v = the integral of acceleration with respect to time.
What does slope of a speed time graph represent?
The slope of a velocity-time graph represents acceleration.
What does the slope of a speed-time graph represent?
The slope of a velocity-time graph represents acceleration.
What is slope of velocity v time graph?
the slope at any point on the graph is the acceleration
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.
What is the meaning of each of the following features of a velocity-time graph the slope of the line?
The slope of a line on a velocity-time graph is acceleration.
The slope of velocity versus time graph gives?
If your graph shows velocity on the vertical axis and time on the horizontal axis, then the slope of the graph represents the acceleration. More specifically, the slope of the graph at a specific point represents the acceleration at that instantaneous point in time. So if the slope of the graph doesn't change (i.e. the graph is a straight line), then the acceleration is constant and doesn't change over time. In calculus, this is represented as the derivative: The derivative of velocity with respect to time equals the acceleration.
What shows acceleration an a speed time graph?
The slope is the acceleration. Acceleration is the time derivative of velocity.
