Which describes an object in projectile motion? check all that apply.
gravity acts to pull the object down.
the object moves in a straight path.
the forward velocity of the object is 0 m/s.
the object’s inertia carries it forward.
the path of the object is curved.
the object moves both forward and up.

A projetile motion is actedupon by two independent forces: the constant downward acceleration due to gravity, and the constant velocity along the horizontal reaction. The first option is correct. The second option is incorrect, the path is always curved. The third option is also incorrect, there must be an initial force to place the object in motion. The fourth option is correct. The fifth option is also correct. The sixth option is correct, which applies to oblique projectiles. Hence, the answers are: the 1st, 4th, 5th and 6th options.
