3.4 Velocity-time Graphs Flashcards
What is the gradient of a velocity-time graph equal to
The acceleration
What does a straight line of positive gradient mean on a velocity-time graph?
Constant acceleration
What does a straight line of zero gradient ( isn’t going up nor down ) mean on a velocity-time graph?
Constant velocity or zero acceleration
What does a straight line of constant negative gradient mean on a velocity-time graph?
Constant deceleration
What does a curve with changing gradient mean on a velocity-time graph?
Change in acceleration/ the acceleration is changing
What does the area under the graph represent on a velocity-time graph?
The total displacement of the object
How would you calculate displacement for changing accelerations?
Count the squares underneath the graph
