how you can find magnitude of velocity from displacement time graph of the object

To find the magnitude of velocity from a displacement-time graph, follow these steps:

1. Identify the displacement-time graph: This graph plots displacement (distance moved) on the y-axis and time on the x-axis.

2. Understand the concept: The slope of the displacement-time graph at any point gives the velocity of the object at that point in time.

3. Find the slope: To find the slope of the graph at a particular point, draw a tangent to the curve at that point. The slope of this tangent line represents the velocity of the object at that point in time.

4. Calculate the slope: The slope of a line is calculated by the formula (change in y) / (change in x). In this case, it would be (change in displacement) / (change in time).

5. Determine the direction: The direction of the velocity is determined by the sign of the slope. If the slope is positive, the velocity is in the positive direction. If the slope is negative, the velocity is in the negative direction.

6. Find the magnitude: The magnitude of the velocity is the absolute value of the velocity, which is the slope you calculated.

Remember, the units of velocity will be the units of displacement divided by the units of time, such as meters per second (m/s).
