*medal*Acceleration as vectors in Projectile motion: In which instances are the acceleration vectors negative, positive, or 0?-a personal question. please be detailed!

Question

anonymous · Answer

for x component and y component of acceleration vector....

anonymous · Answer

@wio help please??

anonymous · Answer

In projectile motion, the horizontal component always has 0 acceleration.

anonymous · Answer

The vertical component always had downward acceleration

anonymous · Answer

in other words, in projectile motion, the horizontal component (velocity) is constant?

anonymous · Answer

Yes.

anonymous · Answer

and direction of projectile launched will not affect either of the components of the acceleration vectors?

anonymous · Answer

No, because a projectile is assumed to be only under the force of gravity.

|dw:1380939075722:dw| so x component of acceleration is 0, and y component of acceleration is negative in this diagram as well then?
