Displacement-Time Graph Flashcards
What does a displacement-time graph say?
It provides important information about the motion of an object.
What does the gradient of a d-t graph tell us?
It gives the average velocity of the moving object.
How can the gradient be found?
Change in displacement / Change in time
What must we note about a steeper gradient?
The greater the velocity.
What shape will the line have if the car is at rest?
Horizontal line
If the car moves at a constant velocity, what shape will the line have?
Straight line
What shape will a non-uniform velocity like?
Just a simple increasing line
What type of line will the graph show if the car is slowing down?
Decreasing line
The average slope of the displacement-time graph is a measure of the _______.
average velocity
The average slope gives the ________ ____ at the mid-point of the interval if acceleration is constant
instantaneous velocity
