Chapter 5.5: Applications of graphs in real world contexts Flashcards
Knowing all the formulas to find the unknown
1
Q
The formula to find distance in Speed-time graph
A
Area under graph:
Area of a triangle = L × H × ½
Area of a rectangle = L x H
OR
Area under the graph:
Area of a trapezium
= ½ × (Base₁ + Base₂) × Height
where Base₁ + Base₂ are the two lengths of paralle
2
Q
The formula to find acceleration in a Speed-time graph
A
gradient = rise/run
gradient = (y2-y1/x2-x1)
3
Q
The formula to find speed in a Distance-time graph
A
gradient = rise/run
gradient = (y2-y1/x2-x1)
