Velocity time graph for uniform motion

A graph plotted with time along the X-axis and the velocity along the Y-axis is called the velocity-time graph. The nature of the graph depends on the nature of the motion of the particle. The velocity-time graph for different cases is explained below. In uniform motion, the velocity of the particle remains the same.

Viva Voce. To plot the velocity—time v — t graph for an object moving with uniform accelerations from a given set of v — t data and to determine the acceleration of the moving object and the distance moved by the object. An object is said to be in motion if it changes its position with time, with respect to its surroundings. The length of the actual path travelled by the object in motion in a given time is known as the distance travelled by the object. Different objects may take different amounts of time to cover a given distance. We can determine how fast or how slow an object is moving by calculating the speed of the object. The s peed of an object is the distance travelled by the object in unit time.

Velocity time graph for uniform motion

The velocity of a body in a uniformly accelerated motion increases by equal amounts in equal intervals of time. This also indicates that it moves at a constant acceleration. Such a graph, when plotted for a moving body, can provide a lot of information about the motion of the body, such as the type of motion, velocity, acceleration, and displacement. The slope is a measure of the steepness of a graph. Consider two points A and B in the position-time graph of a body in a uniform motion and let their coordinates be t 1 , v 1 and t 2 , v 2 , respectively, as shown in the figure below. In fact, the slope of a v-t graph at a particular instant gives the acceleration of the body at that instant. This is because the slope is the ratio of the change in velocity and change in time, which is equal to the velocity of the body. The velocity-time graph may look very different for different kinds of motion. Some of them are as follows:. An object moving at a uniform velocity covers equal distances in equal intervals of time. This is because its velocity remains constant throughout the motion. Such a motion is called a uniform motion. Its v-t graph is a straight line parallel to the x-axis, as shown in the graph below.

Therefore, the v-t graph of a body at rest is a straight line coinciding with the x-axis time-axisas shown in the figure below. If an object moving with an initial velocity u at time 0 attains the final velocity v in time tthen the acceleration a is.

This article will cover the basics for interpreting motion graphs including different types of graphs, how to read them, and how they relate to each other. Interpreting motion graphs, such as position vs time graphs and velocity vs time graphs, requires knowledge of how to find slope. If you need a review or find yourself having trouble, this article should be able to help. There are three types of motion graphs that you will come across in the average high school physics course — position vs time graphs, velocity vs time graphs, and acceleration vs time graphs. An example of each one can be seen below. The position vs time graph on the left shows how far away something is relative to an observer. The velocity vs time graph in the middle shows you how quickly something is moving, again relative to an observer. Finally, the acceleration vs time graph on the right shows how quickly something is speeding up or slowing down, relative to an observer.

Velocity time graph for uniform motion

Our study of 1-dimensional kinematics has been concerned with the multiple means by which the motion of objects can be represented. Such means include the use of words, the use of diagrams, the use of numbers, the use of equations, and the use of graphs. Lesson 4 focuses on the use of velocity versus time graphs to describe motion. As we will learn, the specific features of the motion of objects are demonstrated by the shape and the slope of the lines on a velocity vs. The first part of this lesson involves a study of the relationship between the shape of a v-t graph and the motion of the object. As learned in an earlier lesson , a car moving with a constant velocity is a car with zero acceleration.

The speed of an object moving in a definite direction is known as its velocity. Yes No. Velocity - time graph A velocity-time graph is the graphical representation of the change in velocity of an object with time. The nature of the graph depends on the nature of the motion of the particle. As the change in velocity of the object for any time interval is zero, the slope of the graph is zero. The change in velocity of an object per unit time is known as acceleration. Visible light contains a mixture of wavelengths that the human eye can detect. Viva Voce. The velocity-time graph may look very different for different kinds of motion. Earth and space.

The slope of the v - t graph for object in non-uniform acceleration is different at different points under consideration. The velocity-time graph of a particle moving along a straight line with uniform acceleration may be used to measure the displacement of the particle and also the acceleration. The rate of increase in velocity is more between B and C which is indicated by the steeper slope. In figure 4, the ordinate OA gives the initial velocity and the ordinate BD gives the final velocity. Mar 3, Consider two points A and B in the position-time graph of a body in a uniform motion and let their coordinates be t 1 , v 1 and t 2 , v 2 , respectively, as shown in the figure below. The graph would start from the origin if the body was initially at rest. The larger the slope of the graph, the higher the acceleration of the moving object. If we consider two points, x 1 , y 1 and x 2 , y 2 on the given line, then the slope,. In uniform motion, the velocity of the particle remains the same. Book a free demo. The area under the velocity-time graph between the time t 1 and t 2 shaded portion gives the displacement during the time interval t 1 to t 2 figure 2.
