What does a velocity-time graph represent?

What does a velocity-time graph represent?

A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.

How is velocity represented graphically?

In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. 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. The position of the object is not changing.

What type of motion are represented by the following velocity time graphs?

In the first graph, the graph shows uniform motion as the velocity is constant over the time. In the second and third graph, the graphs show uniform acceleration as the velocity is increasing at a constant rate.

What is the velocity time graph?

A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.

What is represented by slope of velocity time graph?

The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

What is graphical representation of motion give an example graph?

Ans: The representation of the motion of a body moving along a straight line pictorially by a graph is called the graphical representation of linear motion. For example, the displacement-time graph of a car moving along a straight road with a uniform velocity is a straight line that is not parallel to the time axis. Q.

What is velocity time graph 9?

What is Velocity Time Graph. It is used to show Velocity of object and Time Taken on a graph paper. Here, Time Taken is shown on x axis. Velocity is shown on y axis.

What type of motion is represented by the following graphs?

The following graph represents uniform motion in such a way that the body covers a particular distance in a particular time and comes back to initial position in same time.

What is represented by the gradient of a velocity time graph?

The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled. Likewise, the area under a velocity-time graph represents the displacement of the moving object.

What does the y-axis of a velocity time graph represent?

A velocity time graph is what we use to show how velocity changes with time. Time is drawn on the x-axis because it is the variable the scientist chooses to change (independent) and velocity is drawn on the y-axis because it is what the scientist measures (dependent).

Which is an example of a velocity time graph?

Velocity-Time Graphs. The slope of the graph will give the magnitude of acceleration. Example: If the acceleration of a particle is constant (k) and is positive, the initial velocity is zero, and then the velocity increases linearly. The slope of the velocity-time graph will give the acceleration.

What are the different types of time graphs?

Types of Graphs 1 Displacement Time Graph. Displacement of an object is defined as how far the object is from its initial point. 2 Velocity Time Graph. In velocity time graph, velocity is the dependent variable and is represented to the y-axis and time is the independent variable, represented on x-axis. 3 Acceleration Time Graph.

How are displacement and velocity graphs used in physics?

But graphs actually give us a better understanding of the motion. From the point of view of physics one should be able to interpret motion by looking at graphs. Here we will be talking mainly about velocity time graph and displacement time graph. Displacement of an object is defined as how far the object is from its initial point.

Which is an example of a graphical representation of motion?

Ans: The representation of the motion of a body moving along a straight line pictorially by a graph is called the graphical representation of linear motion. For example, the displacement-time graph of a car moving along a straight road with a uniform velocity is a straight line that is not parallel to the time axis. Q.3.
