Infer the motion of a car whose speed-time graph shows a horizontal line followed by a straight line that slopes downward to the bottom of the graph?
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
What type of graph do you use for speed?
Line graph.
What does a direct proportion look like on a graph?
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
Does the slope of the line on a speed time graph tells the speed?
No. The slope on a speed vs time graph tells the acceleration.
What shows the speed on a distance-time graph?
The slope of the graph line or curve.
What will the acceleration-time graph show if the speed is decelerating?
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
The graph of a car's speedometer was straight line sloping downward. the car was?
Slowing down or decelerating
What is a line sloping upwards on a speed time graph tell us?
The object is accelerating
Plot the graph to show ball thrown vertically upward and comes downward ignoring air resistence?
If you want the graph to show the acceleration of the ball against time, then the graph is a horizontal line. If you want the graph to show the velocity of the ball against time, then the graph is a straight line sloping downward. If you want the graph to show the height of the ball against time, then the graph is a parabola that opens downward.
Infer the motion of a car whose speed-time graph shows a horizontal line followed by a straight line that slopes downward to the bottom of the graph?
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
What is a sloping straight line on a distance time graph?
An upward sloping straight line indicates that the object being studied is moving away from the origin and that the component of its velocity in the radial direction is a constant. A downward sloping line indicates it is moving towards the origin. However, neither line says anything about the transverse component of its motion.
What does a downward sloping diagonal line mean in a velocity vs time graph?
This means your velocity is decreasing with time, or in other words, the object is slowing down.
What does a line that is sloping upwards on a speed time graph shows us?
That the object being studied is accelerating in the radial direction.
How do you tell an object is going constant speed on a graph?
That depends on what is graphed. If the graph is location versus time, it will be a sloping straight line through the origin. If the graph shows speed versus time, it will be a horizontal line at any height. If the graph shows acceleration versus time, it will be a horizontal line at the height of zero.
What does a curved line pointing downward on a position versus time graph indicate?
That means the speed (the slope of the position-time graph) is decreasing.
Why a budget line sloping downward?
Because the expenses are greater than the income.
What type of motion is occurring when the slope of a velocity vs time graph is changing?
A motion described as a changing, positive velocity results in a sloped line when plotted as a velocity-time graph. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).
