A.VECTOR AND SCALAR

-VECTOR -has magnitude and direction e.g displacement,velocity,force etc

-SCALAR-has only magnitude e.g distance,speed,temperature etc

RESOLUTION OF FORCE

VECTOR HAS MAGNITUDE AND DIRECTION AND MOST TIMES NEED TO DETERMINE THE RESULTANT FORCE.

ILLUSTRATION

KINEMATICS

-DISPLACEMENT-The distance moved in a particular direction. Given in m

Velocity= change of displacement/time taken. Given in ms-1

Speed=Distance/time taken

Acceleration=Change of velocity/time taken

DIFFERENT TYPES OF FORCES

-Gravitational force

-Electrostatic force

-Magnetic Force

-Normal reactiont

-Compression

-UPtrust

-lift

EQUILIBRIUM

SUMMATION OF FORCE=0

MOMENTUM

RESULTANT FORCE=CHANGE P/CHANGE T

F=Ma=dp/dt
