Question

Toss a ball upward. What is the change in speed each second
on the way up? On the way down?

Answer 1

As you throw the ball up into the air, its direction is up, but the speed decreases due to the pull of gravity. The ball slows down, and at the very top of its flight, its velocity at that instant is zero.

On the way down, its speed increases by about 10 m/s each second.

Step-by-step explanation:

Answer 2

-9.8m/s force of gravity

Step-by-step explanation:

If gravity is the only force acting upon the ball, the ball will have a -9.8m/s acceleration.
