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.

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. Similarly, if the particle moves with a uniform negative velocity, the velocity-time graph will be a straight line below the time axis. The velocity-time graph enables one to calculate the total displacement of the particle in a time interval.

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.

Else, it may start from a point on the x or y- axis or any other point on the cartesian plane.

To draw velocity-time graphs, we will use the three equations of motion. When the velocity is constant, the velocity-time graph, with Y-axis denoting velocity and the X-axis denoting time, will be like:. Put your understanding of this concept to test by answering a few MCQs. Your Mobile number and Email id will not be published. Post My Comment. Velocity-Time Graphs To draw velocity-time graphs, we will use the three equations of motion.

Velocity time graph for uniform motion

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 object moving at a uniform velocity covers equal distances in equal intervals of time. Book a free demo. The velocity of a body at rest is zero until it starts moving. We know that distance travelled by an object is given by the product of velocity and time. Introduction: Nowadays magnets are widely used for many applications. Velocity-time graph for such a motion is represented in the figure below. Key Concepts 1. For non-uniform motion, the velocity of the object varies with time. We can determine how fast or how slow an object is moving by calculating the speed of the object. In this case, the acceleration of an object changes with time. The velocity-time graph of such a motion is as shown in figure 5.

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.

An object moving at a uniform velocity covers equal distances in equal intervals of time. The velocity-time graph may look very different for different kinds of motion. Non - uniform motion Motions where objects cover unequal distances in equal intervals of time are referred to as non-uniform motion. This indicates that the acceleration of the body in such a motion is zero. Visible light contains a mixture of wavelengths that the human eye can detect. Using this graph, one can even determine the velocity or acceleration at a time beyond the range of time intervals given in the data. Different objects may take different amounts of time to cover a given distance. You can also go through my previous article which discussed the meaning and shape of the position-time graph for uniform motion. The slope of the v-t graph of a body moving with increasing acceleration keeps increasing as the steepness of the graph keeps increasing. Also, this article explored the methods to find the displacement and acceleration from the v-t graph. The velocity-time graph of a uniformly accelerated object will therefore be a straight line inclined to the time axis.
