Velocity And Acceleration Flashcards
What is the equation to work out acceleration?
Include units
Acceleration (m/s^2) =
Change in velocity (m/s) /
Time taken (s)
What is velocity?
Speed in a given direction.
How do you work out change in velocity?
Final velocity- original velocity
What does negative acceleration (deceleration) mean?
That the object slows down.
What does a velocity time graph show?
It shows how an objects velocity changes with time.
What does the gradient at the front of a velocity time graph show?
It shows the objects acceleration, a steeper gradient means greater acceleration.
What does a flat line show on a velocity time graph?
A flat line shows that the object is moving a a steady speed.
What does the area under a velocity time graph show?
It shows the distance travelled, to calculate the area think of the shape as a combination of triangles and rectangles.
