Distance-Time Graphs Flashcards
1
Q
The gradient of a line at any point in a distance-time graph tell us the what and why?
A
The speed
This is because the gradient = distance / time which is the same formula for speed
2
Q
What does a flat line tell us about the speed on a distance-time graph?
A
Speed = 0
3
Q
What does a curvy line up tell us about the speed on a distance-time graph?
A
Acceleration
4
Q
What does a curvy line down tell us about the speed on a distance-time graph?
A
Deacceleration
5
Q
How do we calculate the gradient of a curved line?
A
Draw a tangent to that curve and calculate the gradient of the tangent
