distance-time graphs Flashcards
1
Q
what do flat sections show?
A
the object is stationary
2
Q
what do straight uphill sections show?
A
the object is travelling at a steady speed
3
Q
what represents acceleration or deceleration?
A
curves
4
Q
what does a steepening curve show?
A
the object is speeding up (increasing gradient)
5
Q
what does a levelling off curve show?
A
the object is slowing down (decreasing gradient)
6
Q
how can you find an objects speed on a distance-time graph, if it is accelerating?
A
finding the gradient of the tangent at that point
7
Q
what does the gradient represent?
A
speed, the steeper the gradient the faster the object is travelling
because s=d/t
