How to calculate the gradient from the non linear graph?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
How can you find the instantaneous acceleration of an object whose curve on the velocity time graph is a straight line?
It is the gradient (slope) of the line.
What feature of a distance per time graph represents speed?
The gradient (slope) of the tangent to the graph at the given time - provided that it exists. If the graph is a straight line at that point, it is the gradient of that line.
How do you find a gradient of a line without a graph?
Select two values of x: (x1 and x2) within the domain. Solve the equation of the line to find the corresponding values for y: (y1 and y2). Then the gradient = (y1 - y2) / (x1 - x2)
What graph graph indicates that there is a linear relationship between the dependent variable and the independent variable?
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant
