30 kwi 2021 · If you have data for the distance from home at set points in time, then calculating and plotting the distance and point-to-point velocity are straight forward: % time points in seconds when position is measured
It works because displacement is the product of velocity and time. And in our graph when you multiply velocity and time you're basically multiplying two lengths in our graph and that gives us the area. And so that's the secret to calculating displacements and from a velocity time graph.
We can calculate the average speed of something moving if we know the distance it moves and the time it takes: = distance. average speed time. In symbols, this is written as: = d. v. t. where v is the average speed and d is the distance travelled in time t.
We're going to look at position versus time graphs, and use them in order to figure out displacement and distance traveled. So this first question says, a 3.2 kilogram iguana runs back and forth along the ground. The following graph shows the horizontal position of the iguana in meters over time.

Finding distance and displacement from graphs. A baby elephant trots in a straight line along a river. The horizontal position of the elephant in meters over time is shown below.
Worked example. (a) Calculate the velocity of the athlete during the first 2 seconds. (b) Describe the motion of the athlete between the times of 2 seconds and 5 seconds. (c) Calculate the velocity of the athlete at 10 seconds. (d) Find the total distanced travelled by the athlete during the 14 seconds.
