Help me with easy physics question

[aleferesco]

A ball is thrown straight up into the air. At each of the following instants, is the magnitude of the ball's acceleration greater than g, equal to g, less than g, or zero

a) just after leaving your hand? ________

b)At the very top (maximum height)?__________

c) just before hitting the ground?__________

g doesn't change. All of them = g.

 

[aleferesco]

even though when the ball leaves your hand is still equal to g, wouldn't it be greater??

 

[musicfairy]

You are thinking about velocity. That changes, but g does not. g is the change in velocity near the surface of earth. If you're still confused you should read your textbook. All of them gives a good description of g.
