When a ball is thrown straight up, is there any point at which the ball has zero acceleration?
No, the acceleration is constant at every point of it's trajectory
always -9.8 velocity can be zero at the top
the ball accelerates downwards with gravity over the entire trajectory
Ya krypton is correct. Acceleration is always -9.8 for moving against gravity
No never becaz acceleration is always -9.8 m/s^2...but velocity varies...
