FORCES + NEWTONS LAWS
-
-
-
-
NEWTONS 2nd LAW: F = ma; acceleration is proportional to resultant force, inversely proportional to mass.

-
MOMENTUM AND COLLISIONS
-
-
In a closed system, total momentum before = total momentum after
-
Inelastic collisions: momentum conserved , KE not conserved
-
ACCELERATION
-
-
-
-
INSTANTANEOUS ACCELERATION =the rate of change of an object's velocity at a specific instant in time
