A1.2 Motion Graphs Flashcards
1
Q
what do displacement-time graphs tell us
A
the positioning of an object over time
2
Q
what do velocity-time graphs tell us
A
the velocity of an object over time
3
Q
how can we draw a velocity-time graph
A
we can draw it by using direct measurements of velocity or generated from calculations made using displacement time-graphs
4
Q
can distance-time graphs decrease over time
A
no, because they dont have a direction
5
Q
can displacement- time graphs decrease over time
A
displacement-time graphs can have a negative value if the object went the opposite direction
6
Q
how can we find velocity in displacement-time graphs
A
the gradient = change of displacement/time taken to change displacement
7
Q
how to find the distance from a velocity-time graph
A
by calculating the area under the graph
