Q
Velocity
A
s/t (distance/time)
2
Q
Accelleration
A
a= v-u/t (final velocity-intitial velocity / time)

4
Q
distance
A
How far an object has moved. It’s a scalar quantity.
5
Q
Displacement
A
The distance AND the direction. It is a vector quantity.
6
Q
Distance travelled (s)
A
Speed (v) x time (t)
7
Q
Gradient in a distance time graph
A
The gradient indicates the speed. The steeper it is the faster an object is travelling. Straight sections show constant speed and curved sections show acceleration or decceleration.
8
Q
Velocity time graphs
A
Gradient is acceleration. A flat line is a constant speed and a diagonal line is increase or decrease in velocity (constant acceleration). Curves are increases or decreases in acceleration.
