Using and Interpreting graphs Flashcards
1
Q
What can have a meaning on a graph?
A
The gradient, the value of y or the area under the graph.
2
Q
On a displacement vs time graph, what is the gradient?
A
The velocity
3
Q
On a velocity vs time graph, what is the gradient?
A
The acceleration
4
Q
On a velocity vs time graph, what is the area under the curve?
A
The displacement
5
Q
On a curve, what happens to the gradient?
A
It changes.
6
Q
What is a tangent line?
A
A line that touches the curve exactly once. It can find a precise gradient on a single point.
7
Q
What is an instantaneous gradient?
A
A gradient at a single point as opposed to a gradient between two points.
8
Q
How can you estimate the area under a curve?
A
You can draw rectangles or trapeziums to discover an approximate value for the area.
