Section 2 - Kinematics Flashcards
1
Q
Mean speed
A
Total time
Unit: ms^-1
2
Q
Displacement
A
The distance from the origin (in a straight line), together with the direction.
3
Q
Mean Velocity
A
Total time
4
Q
Mean acceleration
A
Time taken
5
Q
Displacement-time graph
A
Instantaneous Velocity = gradient of tangent
Average Velocity = straight line between two points and gradient
6
Q
Velocity-time graph
A
Gradient = acceleration Area = distance travelled
7
Q
Displacement » Velocity » Accel
A
Gradient = velocity Accel = v-u/t
8
Q
Accel » velocity » displacement
A
Vel = area under a-t graph Distance = area under v-t graph
9
Q
S.U.V.A.T.
A
V=u+at S=(v+u/2)t V^2=u^2 +2as S=ut+1/2at^2 S=vt-1/2at^2
