1Define distance (d)How far travelled in total in metres (scalar)
2Define displacement (s)How far from the starting position you are in metres (vector)
3A negative displacement represents what direction?Backwards
4What are the 2 types of velocity?Average velocity and instantaneous velocity
5Define instantaneous velocityThe velocity of an object at a precise moment (it's equivalent to average velocity over a short period of time and is calculated the exact same way)
6How do you calculate velocity is ms-1?velocity = change is displacement / change in time
7On a displacement time graph, constant velocity is represented by a....Diagnol, straight line
8On a velocity time graph, constant velocity is represented by a....Horizontal straight line
9On a displacement time graph, a stationary position is represented by a.....Horizontal straight line
10On a velocity time graph, a stationary position is represented by a....Line going all the way back to 0
11If a displacement time graph goes back through the axis to a negative value, the direction is....Backwards
12If a velocity time graph goes back through the axis, it represents....A backwards movement (as velocity is negative)
13What is the formula for acceleration?Acceleration = change in velocity / change in time
(in ms-2)
14Define accelerationThe rate of change of velocity
15The gradient of a displacement time graph = ....Velocity
16The gradient of a velocity time graph = ....Acceleration
17Area under a velocity time graph = ....Distance
