Accelation

Accelation is the rate of change of velosity, it means to increasing speed or decreasing speed or changing direction.

Balance and unbalance forces.
  Forces occur in pairs, it could be either balance or unbalance.
-Forces in the opposite direction combine by subtraction.
-Balance force do not cause a change in motion.

-Unbalance force always cause a change in motion.
-Force in the same direction combine by addition.
P.S= Different direction မွာ balance force ျဖစ္ေနရင္ motion မျဖစ္။
        Same direction မွာ balance force ျဖစ္ျဖစ္ unbalance force ျဖစ္ျဖစ္ motion ျဖစ္တယ္။
