What is the nature of motion with velocity-time graph?

Answer Expert Verified. The nature of the velocity-time graph for a uniform motion would be a straight horizontal line where velocity would be the Y axis, and time would be the X axis. The reason is that velocity would be constant, and will not increase or decrease in a uniform motion, whereas time would pass by.

What does a velocity-time graph show you about an object?

The slope of a velocity-time graph reveals information about an object’s acceleration. But how can one tell whether the object is moving in the positive direction (i.e., positive velocity) or in the negative direction (i.e., negative velocity)? And how can one tell if the object is speeding up or slowing down?

What can you conclude about how a velocity vs time graph represents the movement of an object?

The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

What does velocity tell us about the motion of an object?

Velocity is a measure of both speed and direction of motion. The average velocity of an object moving in a constant direction is calculated with the formula: velocity=distancetime. The SI unit for velocity is m/s, plus the direction the object is traveling.

What is the nature of motion if velocity of an object is decreasing with time?

if the velocity of the object decreases with time, the acceleration is negative, and the motion is called decelerated motion. true or false , give reason for your answer​

What is the nature of velocity time graph of an object moving with a velocity decreasing uniformly?

Answer: The slope of the velocity time graph of an object moving with uniform decreasing velocity with uniform acceleration is a downwards straight line.

What do motion graphs tell?

The slope of a motion graph tells us the rate of change of the variable on the vertical axis, so we can understand velocity as the slope of the position vs. time graph.

How can a graph help you understand an object’s motion?

Summary: A speed – time graph shows us how the speed of a moving object changes with time. The steeper the graph, the greater the acceleration. A horizontal line means the object is moving at a constant speed. A downward sloping line means the object is slowing down.

What can you conclude when a position time graph is curved?

If a position graph is curved, the slope will be changing, which also means the velocity is changing. Changing velocity implies acceleration. So, curvature in a graph means the object is accelerating, changing velocity/slope.

What do you notice about the graph of acceleration vs time?

An acceleration vs. time graph plots acceleration values on the y-axis, and time values on the x-axis. time graph, the slope at that point (derivative) will always be equal to the acceleration at that time. So, if at some moment your acceleration is positive, then at that moment your velocity will be increasing.

What do you need to know to describe the velocity of an object?

One must include direction information in order to fully describe the velocity of the object. For instance, you must describe an object’s velocity as being 55 mi/hr, east. This is one of the essential differences between speed and velocity.

What is a velocity-time graph of a moving object?

A velocity-time graph of a moving object is a straight line inclined to the time axis. What do you conclude about the nature of motion? – Quora A velocity-time graph of a moving object is a straight line inclined to the time axis.

What happens if acceleration is negative on a velocity time graph?

If the acceleration is negative, then the slope is negative (i.e., a downward sloping line). This very principle can be extended to any conceivable motion. The slope of a velocity-time graph reveals information about an object’s acceleration.

Why do we need graphs to understand motion?

But graphs actually give us a better understanding of the motion. From the point of view of physics one should be able to interpret motion by looking at graphs. Here we will be talking mainly about velocity time graph and displacement time graph. Displacement of an object is defined as how far the object is from its initial point.

What is the difference between 2 and 3 in velocity graph?

2: The object is moving at a constant velocity in the positive direction. Here, position and time are changing at a constant rate, upwards. The velocity graph is horizontal, above the time axis. Now, you are walking a steady pace forward. 3: The object is moving at a constant velocity in the negative direction. These graphs are the opposite of #2.
