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.

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.

Velocity time graph for uniform motion

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. When an object travels equal distances in equal intervals of time, it is said to be in uniform motion.

This also indicates that it moves at a constant acceleration. The plot of velocity and time for such a motion is curved in a way shown in the figure below. Thereafter, let the velocity of the car decrease uniformly and the car come to a stop at the instant t 4.

It is a useful tool for analyzing the motion of objects and understanding their acceleration. In a velocity-time graph, the velocity is plotted on the y -axis, while time is plotted on the x-axis. A horizontal line on the graph indicates that the object is moving at a constant velocity. A velocity-time graph, also known as a speed-time graph or motion graph, is a graphical representation that shows how the velocity of an object changes over time. In this graph , the velocity of the object is plotted on the y -axis, while the time is plotted on the x-axis. They allow us to analyze various aspects of the motion, such as acceleration, deceleration, constant velocity, and changing velocity. A positive slope indicates positive acceleration, a negative slope indicates negative acceleration deceleration , and a zero slope indicates zero acceleration. The displacement can be positive, negative, or zero, depending on the direction of motion.

Velocity time graph for uniform motion

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.

Consider a particle moving along a straight line with uniform acceleration a. Students gain the ability to infer information from a graph. Ways to Simplify Algebraic Expressions Nov 26, How to Find the Area of Rectangle? For non-uniform motion, the velocity of the object varies with time. 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 s peed of an object is the distance travelled by the object in unit time. The v - t graph plotted here shows the motion of the object for a given range of time interval. Also, this article explored the methods to find the displacement and acceleration from the v-t graph. Hence, the velocity-time graph for an object in uniform motion is a straight line parallel to the time axis. In this session, we will calculate this force that makes one team win and one team lose. The v-t graph of such a motion, when plotted, turns out to be a straight line with a negative slope. An object in non-uniform acceleration Velocity-time graph for such a motion is represented in the figure below. Mar 3, Biology Science Earth and space.

Our study of 1-dimensional kinematics has been concerned with the multiple means by which the motion of objects can be represented.

Sign Up. That is, Some examples of Velocity - Time graph An object in uniform motion The speed of such an object is constant. The slope of the v - t graph can give a comparison of the acceleration of different moving objects. Conventionally, the x-axis represents time, and the y-axis represents velocity of the object. If the acceleration of the object increases, the slope of the graph increases. 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. How do you express instantaneous velocity of a body in non-uniform motion along a straight line? In figure 4, the ordinate OA gives the initial velocity and the ordinate BD gives the final velocity. Velocity-Time v - t Graph. An object is said to be in motion if it changes its position with time, with respect to its surroundings.
