velocity-time graphs Flashcards
1
Q
what does the gradient represent?
A
acceleration, because a=change in velocity/time
2
Q
what do flat sections represent?
A
the object is travelling at a steady speed
3
Q
how is a greater acceleration/deceleration represented?
A
a steeper gradient
4
Q
what do uphill sections represent?
A
acceleration
5
Q
how is deceleration represented?
A
by downhill sections
6
Q
what does a curve mean?
A
changing acceleration
7
Q
what is the area under any section of the graph equal to?
A
the distance travelled in that time interval
8
Q
how would you find the distance travelled in any number of seconds?
A
work out the area underneath the graph between the time interval given
