Distance-time graphs show distance on the vertical axis ... The speed is 8 miles per hour because speed is always a positive value. The velocity, however would be -8 miles per hour because the ...

Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the ...

Let's make another graph. First, I am going to put distance on the ... this is with a zero initial velocity. However, if you use other methods to collect position-time data then there could ...

Here is a velocity vs time graph for this same situation. As you can see from this plot, the distance traveled would be equivalent to the area under the velocity-time graph. OK, so what if the ...

Lidar measures distance, while radar provides a precise estimate of velocity. This is a bit of an oversimplification, of course. The physics of the situation makes it possible to measure either ...
