An object accelerates in a direction that is always perpendicular to its motion.
what is the effect, if any, of the acceleration on the object’s speed and direction?

I think the effect is circular motion. well, the speed may or may not change. the direction of acceleration is always tangential to the circular path.

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.
