forces - distance time graphs Flashcards
1
Q
when can the distance travelled by represented by a distance time graph?
A
when an object moves along a straight line
2
Q
what does the gradient of a distance time graph tell us?
A
the object’s speed
3
Q
how to calculate gradient on distance time graph?
A
distance travelled / time taken
4
Q
what does an upward sloping curve on a distance time graph tell us?
A
the object is constantly increasing in speed (accelerating)
5
Q
how to calculate speed on a curve?
A
- draw a dot on the line for the time you want
- draw a tangent to the line. it should be large
- then work out gradient of line/tangent
