Graphs Flashcards
What will the graph show if the object is stationary on a distance time graph?
A horizontal line
What is shown on a distance time graph if the object is travelling at constant speed?
A straight line sloping upwards
What is velocity?
Speed in a given direction
What happens to velocity of an object changed direction?
It also changes
What is it called when an objects velocity changes?
Acceleration
What is deceleration?
A negative acceleration (slowing down)
What does the gradient of the line represent in velocity time graphs?
Acceleration
What acceleration does an object have if its line on a velocity time graph is horizontal?
Zero (constant speed)
If the line’s gradient is negative on a velocity time graph what does this show?
The object is decelerating
What is the area under the line on a velocity time graph?
The distance travelled
What represents the speed in a distance time graph?
The gradient
