Matthew throws a ball straight up in the air it rises for a period time then it begins to drop at which point in the balls journey will gravity be greatest force acting on the ball?

The greatest force of gravity on the ball will occur at the point when the ball is near to hit the ground.

As we know that the earth's center attracts everything towards its center with an acceleration of 9.8 m/s² so it simply means that the change in velocity must occur to produce acceleration. When the ball comes towards the earth, its speed contineously increases and it is at maximum level when it is about to hit the ground so this is the point where gravitational force is maximum.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
