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.

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.

If the body is brought to rest, the graph will touch the time axis. Order of Magnitude.

.

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. Case 1: Velocity-time graphs with constant velocity zero acceleration When the velocity is constant, the velocity-time graph, with Y-axis denoting velocity and the X-axis denoting time, will be like: As the graph shows, the velocity is constant c throughout the interval. No particles of matter how much the time changes, the velocity will be c at every instant.

Velocity time graph for uniform motion

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.

If the acceleration of the object increases, the slope of the graph increases. Explanation: Types of Waves: Fig:1 Types of waves […]. We will learn about it in terms of balanced force and unbalanced force. The v-t graph of such a motion, when plotted, turns out to be a straight line passing through the origin if the body starts from rest with a positive slope. The v-t graph might also look different in other cases. How to Solve Right Triangles? A velocity-time graph is the graphical representation of the change in velocity of an object with time. 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. Order of Magnitude. Then the area under the velocity-time graph gives the total displacement of the car. Consider a particle moving along a straight line with uniform acceleration a. Assuming two points t 1 , v 1 and t 2 , v 2 , the slope or acceleration of object, 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. A graph plotted with time along the X-axis and the velocity along the Y-axis is called the velocity-time graph. The area under the v - t graph gives the distance travelled.

The slope is a measure of the steepness of a graph. When an object travels equal distances in equal intervals of time, it is said to be in uniform motion. Students learn to find the slope of the graph. We will learn about it in terms of balanced force and unbalanced force. Its v-t graph is a straight line parallel to the x-axis, as shown in the graph below. Learning Outcomes Students learn to plot velocity — time graph of an object from the given data. The larger the slope of the graph, the higher the acceleration of the moving object. Students gain the ability to infer information from a graph. The slope of the v-t graph of a body moving with decreasing acceleration keeps decreasing as the steepness of the graph keeps decreasing. The slope of the v - t graph can give a comparison of the acceleration of different moving objects.
