Acceleration The slope of the line of a speed-versus-time graph will give you acceleration.
Gradient of the 2-d function f(x, y) = xe is plotted as blue arrows over the pseudocolor plot of the function. Consider a room in which the temperature is given by a scalar field, T, so at each point (x, y, z) the temperature is T(x, y, z) .(We will assume that the temperature does not change over time.) At each point in the room, the gradient of T at that point will show the direction the temperature rises most quickly.he steepness of the slope at that point is given by the magnitude of the gradient vector. The gradient can also be used to measure how a scalar field changes in other directions, rather than just the direction of greatest change, by taking a dot product. Suppose that the steepest slope on a hill is 40%.
