Question

What is the acceleration of a ball thrown straight upward on the way up? At the top of its flight? On the way down?

science physics

Answer 1

Answer #1

Velocity: ZERO
acceleration: always 9.8m/s(2)

The speed starts to decrease until it reaches zero at the highest point and then it starts to increase again when the ball goes back downwards.

The acceleration is constant, always 9.8m/s2 downwards, that's why the ball goes speeding down when upwards and speeding up when downwards.
