Edexcel AS Maths Mechanics Vectors and Motion Notes

Just some notes I made for myself to remember the principles and the key points for vectors and motion.

I hope you find this useful. I should be posting up the 'Statics, Dynamics and Moments' notes up soon, too.

M1 Vectors and Kinematics Key Notes
Scalar Magnitude
Vector Magnitude and Direction
Vectors are added by using the triangle law of
addition. In other words, you draw the vectors
from `tip-to-tail' and draw in the resultant.
In terms of i and j notation,
Resultant = Xi + Yj
If particle A has position vector rA and particle B has position vector rB, then the
position vector of B relative to A is rB - rA
If particle A has velocity vector vA and particle B has velocity vector vA, then
the velocity vector of B relative to A is vB - vA
For a particle with constant acceleration:
For Velocity-Time graphs, the AREA under the graph
in a given time interval is the DISTANCE travelled.
The GRADIENT of the graph is the ACCELERATION
of the moving particle.
