Chapter 9: Speed And Distance-Time Graphs Flashcards
1
Q
What is the equation for the speed of an object?
A
Speed (m/s) = distance travelled (m) / time taken (s)
Triangle = s=v
2
Q
In a distance time graph what will the line look like for an object that is stationary?
A
Is a horizontal line
3
Q
In a distance time graph what will the line look like for an object that is moving at a constant speed?
A
It is a straight lime sloping upwards
4
Q
What does the gradient on a distance time graph represent?
A
It represents an objects speed
5
Q
What is velocity?
A
Is speed in a given direction
6
Q
What is the equation for acceleration?
A
Acceleration (m/s squared) = change in velocity (m/s) / time taken for the change (s)
7
Q
What is deceleration?
A
The change in velocity per second when an object slows down
