Time Graph: A graph that illustrates how the velocity of an object varies with time. Q: Can slope alone determine an object’s acceleration? A: Yes, the slope of a curved position-time graph can indicate changing velocity and, consequently, acceleration. pie chart B. We will examine a few other graphs to see if this a In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. Chapter 1 of Lehninger's Principles of Biochemistry, covering the foundations of biochemistry, cell structure, and evolution. Position vs. So in question 8 negative slope i. Graphing Position and Time The motion of an object can be represented by a position-time graph like Graph 1 in the Figure below. e. In these graphs, the position of the object is represented by the vertical axis, the time elapsed is represented by the horizontal axis, and the dependent variable, that is position, depends on the independent variable, that is time. ammeter C. . The slope at any point on a position-versus-time graph is the instantaneous velocity at that point. The procedure for calculating slope is clearly explained and modeled using three sample calculations. The slope is calculated as the change in position ($$\Delta y$$Δy) divided by the change in time ($$\Delta x$$Δx). The slope of the straight-line graph is the same irrespective of the interval which is chosen. The horizontal axis typically represents time, while the vertical axis represents position. The graph for uniform motion of a body is shown in the figure. The position-time graph would look like the graph at the right. A position-time graph helps find other physical quantities, such as velocity. The graph shows how far Ashley was from her house after each min of her trip. We can represent the motion of an object by using a displacement–time graph. speedometer B. If this problem persists, tell us. (dy/dx) = -3 represents that the train is moving in opposite direction to its intended direction. We would like to show you a description here but the site won’t allow us. CK12-Foundation CK12-Foundation Jun 3, 2020 · Find an answer to your question a) What does the slope of position time graph represent. Question 21: Planck's Quantum law does not relate to vector addition, so it is correctly identified as not being a procedure for vector addition. Learn how to determine slope for position vs. There is no acceleration so the car did not change speed the only thing that changed is the position of the car. In this type of graph, time is always plotted on the x-axis and the position is plotted on the y-axis. You need to refresh. Try sliding the dot horizontally on the graph below to see the position at different times. For example, if you read the y -value of the graph below at a particular time (in seconds), you will get the position of the object (in meters) at that instant. The shape and the slope of the graphs reveal information about how fast the object is moving and in what direction; whether it is speeding up, slowing down or moving with a Jan 1, 2026 · In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. In this type of graph, the y-axis represents position relative to the starting point, and the x-axis represents time. Ashley stopped to talk to her friend during her trip, how long did she stop for? On Saturday, Ashley rode her bike to Question 20: The slope of a velocity-time graph represents acceleration, highlighting how quickly velocity changes with time. line graph D. 23) What does the slope of a position-time graph represent? a) displacement b) speed c) velocity d) acceleration e) distance d Aug 13, 2023 · Q: What does a zero slope signify on a position-time graph? A: A zero slope signifies that the object’s speed is momentarily zero, indicating a momentary state of rest. In these graphs, the vertical axis represents the position of the object while the horizontal axis represents the time elapsed: the dependent variable, position, depends on the independent variable, time. Jan 1, 2026 · Q: What’s missing from the graph being drawn in the picture above? A: The x- and y-axes are missing. By examining the slope of the graph, one can determine the object's velocity, and the shape of the graph provides insights into the object's motion characteristics, including whether it is at rest A position-time graph is a way to represent the motion of an object. time graph represents On Saturday, Ashley rode her bike to visit Maria. voltmeter 8. The velocity of an object can be calculated from a position-time graph by finding the slope of the line. The x-axis represents the time and the y-axis represents the position of the object relative to a defined zero position (often where the object started its journey from). If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity.
