This is the line which is tangent to the velocity curve at the 1 s mark. Its slope is visibly less than 0.5 m/s. By measuring the slopes of the tangent lines to the curve at every second during the ...

In physics, displacement is a key concept that allows us to measure an object’s overall change in position. One way to determine such displacement is by analyzing a velocity-time graph. In this ...

If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve.

On the graph of velocity vs. time, Δ v /Δ t is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before ...

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.
