You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.
As the ball rises from point 1 to point 3 it slows down - This is True

In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
no it usually slows down

Friction slows things down.
It usually lowers their effectiveness, i.e. slows the reaction rate.
If you start to be more active like excersise wise it usually slows down, birth contol pills slows it down too...
Whenever another force - usually friction - slows it down.

Engine brake retarders (found usually on commercial vehicles) are intended to inhibit the camshaft's turning, which, in turn, slows down the turning of the driveshaft, which, in turn, slows the rotation of the tires, which, in turn, slows the vehicle down. This is the system commonly known as the "Jake brake".
Refrigeration actually slows down the process of molding, because mold usually grows in damp muggy areas, some temperatures actually slows down some important chemical reactions.
When meteoroids enter Earth's atmosphere they are usually traveling around 10-70 kilometers per second. The atmosphere quickly burns up smaller ones and slows larger ones down to around 300 kilometers per hour before they strike the Earth.
dyeing and then being in the right place at the right time. this usually means they died in or near water. water slows down decomposition. after that it needs to get buried in sediment. this further slows down decomp
