CH 2- Speed, Displacement, Velocity Flashcards
1
Q
Displacement
Symbol is s
A
Distance in a given direction
2
Q
Velocity
Unit is meter per second
A
The rate of change of displacement with respect to time
Time taken
= Average velocity
3
Q
Distance-time graph
A
For an object moving with constant velocity is a straight line
The curve is the speed of the object
Slope = s2 - s1
——-
T2 - t1
4
Q
A velocity time graph shows magnitude of velocity of object against time
Rules are:
A
Constant acceleration is a straight line
Slope is the acceleration
Area under graph is distance travelled
5
Q
Speed
DADS ------------------- SILLY TRIANGLE
A
Speed is the rate of change of distance with respect to time
Metres per second
