What is the meaning of the y-intercept in the equation of the line on the velocity-time graph?
It means that the object was travelling away from or towards the point of reference with a velocity represented by the intercept at the start of the measurement, that is, at time t = 0.
What physical property does the vertical intercept represent?
If x is horizontal distance in your graph, and y is vertical distance, the vertical intercept is what y is when x=0. For example, if x is the time since you started a business, and y is how much your business is worth, the vertical intercept is how much money you started off with.
How do you know there is no motion on a distance time-graph?
distance = velocity x time so on the graph velocity is slope. If slope is zero (horizontal line) there is no motion
What is represented by an x-intercept on a position time graph?
In such graphs the x-axis is usually (but not always) the time axis. The x-intercept represents the time(s) at which your position is at the starting point - either for the first time or later.
What does constant speed appear as on a V-t graph?
On a graph of velocity and time, a constant speed would appear as a straight horizontal line.
What is the y-intercept of the velocity time graph?
The velocity of the object at time = 0
What is represented by an x intercept on a velocity time graph?
If time is the x-axis as expected then the x-intercept would be zero movement of the velocity.
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
Not necessarily. The graph of instantaneous velocity versus time may or may not have a Y-axis intercept of zero. It depends on the initial conditions and motion of the object. If the object starts from rest, then the initial velocity is zero, and the graph will have a Y-axis intercept at zero.
Where must the average velocity for an interval be plotted on a velocity-time graph to represent an instantaneous velocity?
The average velocity for an interval must be plotted at the middle of the time interval to represent an instantaneous velocity on a velocity-time graph.
What physical property does the slope of a velocity time graph represent?
velocity.
What does a slope of a time graph represent?
The slope of a velocity-time graph represents acceleration.
What does the slope of a curve represent on a velocity-versus-time graph represent?
The slope of the speed/time graph is the magnitude of acceleration. (It's very difficult to draw a graph of velocity, unless the direction is constant.)
What does slope of a speed time graph represent?
The slope of a velocity-time graph represents acceleration.
What does the slopeof the lineon a distances time graph represent?
Velocity.
What does area of acceleration time graph represent?
change in velocity
If the velocity is constant describe the slope of the graph on a position vs. time graph.?
If velocity is constant, the slope of the graph on a position vs. time graph will be a straight line. The slope of this line will represent the constant velocity of the object.
What is the meaning of the y-intercept in the equation of the line on the velocity-time graph?
It means that the object was travelling away from or towards the point of reference with a velocity represented by the intercept at the start of the measurement, that is, at time t = 0.
