What is the acceleration of a projectile fired vertically upwards? Is it positive or negative?
Vertically downwards?

  • Physics -

    gravity always accelerates objects toward the center of the Earth

  • Physics -

    That is what I was thinking. I just was not sure if firing the object made a difference.

  • Physics -

    Either way it's -9.8m/s2 since it is slowing down due to the acceleration of gravity if thrown upwards. The same with vertically downwards, it's accelerating downwards -9.8m/s2 due to the acceleration of gravity.
