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.

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. For a particle moving with uniform velocity, the graph is a straight line AB parallel to the time axis X-axis as shown in figure 1.

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. As the SI unit for distance is meters and time is in seconds, the SI unit of speed is metre per second. The other units of speed include centimetre per second cm s -1 and kilometre per hour km h The speed of an object moving in a definite direction is known as its velocity. The velocity of an object can be uniform or variable.

If we consider two points, x 1y 1 and x 2y 2 on the given line, then the slope.

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 learning objectives in this section will help your students master the following standards:. Ask students to use their knowledge of position graphs to construct velocity vs. Alternatively, provide an example of a velocity vs. Ask—Is it the same information as in a position vs.

For non-uniform motion, the velocity of the object varies with time. For example, the graph below shows the v-t graph of two bodies in uniform motion at different accelerations. Contents 1 Velocity time graph for uniform motion 1. For a particle moving with uniform retardation or deceleration, the velocity-time graph will be a straight line having a negative slope as shown in figure 7. The velocity-time graph of a uniformly accelerated object will therefore be a straight line inclined to the time axis. The other units of speed include centimetre per second cm s -1 and kilometre per hour km h This is because its acceleration remains constant but negative throughout its motion. If the acceleration of the object remains the same at all instants of time, then the object is said to be in uniformly accelerated motion. As the SI unit for distance is meters and time is in seconds, the SI unit of speed is metre per second. The nature of the graph shows that the velocity changes by equal amounts in equal time intervals. For example, consider a car starting from point A. Students learn to distinguish the velocity — time graph of uniform motion, uniform acceleration, and non-uniform acceleration. This is because its velocity remains constant throughout the motion. The distance travelled by car in a time interval t 2 — t 1 will be given by the area ABCDE under the velocity-time graph.

It serves as a foundational concept in physics, particularly in the study of mechanics. The purpose of this article is to give readers a thorough understanding of uniform acceleration by looking into its definition, characteristics, kinematic equations, graphical representations, and real-world examples. If the velocity of a body changes by an equal amount in an equal interval of time, however, small the interval may be then its acceleration is said to be uniform.

Earth and space. Hence, an object with a larger area under the v - t graph will have travelled a greater distance. This means that the displacement of an object in the time interval t 2 — t 1 is numerically equal to the area under the velocity-time graph between instants t 1 and t 2. Are you sure you want to logout? 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. An object moving at a uniform velocity covers equal distances in equal intervals of time. Rate this post. Let it be moving along a straight line with uniform acceleration a during the time interval t 1 to t 2 and then start moving with uniform velocity during the interval of time t 2 to t 3. If the particle has an initial velocity the graph will be a straight line, but will not pass through the origin as shown in figure 4. The graph would start from the origin if the body was initially at rest. The velocity of a body in a uniformly accelerated motion increases by equal amounts in equal intervals of time. The other units of speed include centimetre per second cm s -1 and kilometre per hour km h
