Graph Analysis Flashcards
What goes on the x-axis
Independent variable ( the thing you change)
What goes on the y-axis
Dependent variable (thing you measure)
Directly proportional
Positive gradient
Goes through the origin
Proportional
Positive gradient
Does not go through the origin
Inversely proportional
Negative gradient
Non-proportional
Curved gradient
What is the gradient of a distance/time graph
The speed
A directly proportional distance/time graph represents…
…a constant speed
A steep proportional distance/time graph represents…
…accelerating speed
A gently slopping proportional distance/time graph represents…
…decelerating speed
A plateaued distance/time graph represents…
…at rest/stopped
What is the gradient of a velocity/time graph
The acceleration
What is the equation for gradient
Gradient =rise (divided by)run
