1.3 Distance/Time Graphs Flashcards
1
Q
What do distance/time graphs show?
A
How far an object has travelled in a given time
2
Q
What are on the axis of a distance/time graph?
A
x axis - time
y axis - distance
3
Q
How do you calculate average speed?
A
Distance / time
4
Q
What does the gradient show?
A
The speed of the object
5
Q
What does a straight line represent on a d/t graph?
A
A constant speed
6
Q
How does the value of the g gradient relate to speed?
A
The stepper the slope, the faster the speed
7
Q
What does a flat section represent?
A
The object is not moving
8
Q
What does a curve represent?
A
Acceleration (if the gradient is increasing) or deceleration
9
Q
How do you estimate speed for an accelerating object?
A
Draw a tangent to the curve then find the gradient of the tangent
