A bullet is fired into the air.
If all friction and resistance is negligible, which of the following statements are true:
A) Energy of the bullet and acceleration remain constant
B) Energy varies and acceleration remains constant
C) Energy constant while acceleration varies
D) Evergy and acceleration both vary.
Dosn't the projectile gain potential energy as it moves up, and lose KE as it goes down, so its energy varies?
