Accleration And Graphs Flashcards
What is acceleration? What is deceleration?
This is the change in velocity over time. Deceleration is just a negative acceleration.
What is uniform acceleration? How does this apply to gravity?
It is constant acceleration and it is due to gravity, when an object free falls they have a constant acceleration.
What does the different stages tell us In a distance time graph?
The gradient at any point shows the speed of an object
Flat sections means they have stopped moving
Curves represent acceleration
A steeper graph shows it is getting faster
A curve getting steeper or levelling off shows a change of acceleration
What does the different stages in a velocity time graph tell us?
The gradient shows the acceleration
Flat sections show a steady speed
The steeper the graph the greater the acceleration and vice versa
A curve shows a change in acceleration
The area of any section shows the distance travelled
