A-1) A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. Usually, a double displacement reaction results in precipitate formation.
A-2) If an object is moving with constant velocity, then.
Displacement = velocity x time.
If an object is moving with constant acceleration then the equation of third law of motion used to find displacement:
S = ut + ½ at²
S = v2−u22a.
If v = final velocity,
u = Initial velocity.
s = displacement.
A-3) Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.
