Question

If gravity did not affect the path of a horizontally thrown ball, the ball would ____.
a. go straight up
c. fall straight down
b. travel horizontally
d. follow a curved path Please select the best answer from the choices provided A B C D

Answer 1

Gravity is the ONLY force on the ball.  If gravity were not there,
there would be no forces at all acting on the ball. 

You have learned that when no forces act on an object, the object
continues moving in a straight line at a constant speed.

Haven't you ?

Answer 2

Answer:

b. travel horizontally

If an item was thrown horizontally and there is no gravitational pull it to move towards the core of the Earth it will just move horizontally forever, so the answer is "b. travel horizontally "

Hope this helps :)
