Question

Matthew throws a ball straight up into the air. It rises for a period of time and then begins to drop. At which points in the ball’s journey will gravity be the greatest force acting on the ball?

Answer 1

fall to the ground

Step-by-step explanation:

hope this help

Answer 2

Force due to gravity will be maximum when ball is nearest to the surface of Earth

Step-by-step explanation:

As we know that the force due to gravity is given by

`F = mg`

here

m = mass of object

g = acceleration due to gravity of earth

here acceleration due to gravity of earth varies with height from the surface and given as

`g = (GM_(earth))/((R+h)^2)`

so as object moves away from the surface of earth the force of gravity will decreases and when object is nearest to the surface then it is maximum
