Curvy Distance-Time Graphs Flashcards
1
Q
What is the instantaneous velocity of an object?
A
Is its instantaneous speed together with an indication of direction
2
Q
What does it mean if a distance-time graph is curved?
A
The speed of an object is changing
3
Q
What does the curve make it difficult to do?
A
Work out the instantaneous speed
4
Q
What can you still work out from the graph?
A
The average speed
By dividing the total distance by the total time
5
Q
What does a dashed line mean on a curved distance-time graph?
A
It shows the gradient
6
Q
What happens when the gradient is steeper than the dashed line?
A
The object is travelling faster than the average speed
7
Q
What happens when the gradient is less steep than the dashed line?
A
The object is travelling slower than the average speed
