If you throw a ball straight up in the air will the ball come back down at the same speed?

When you throw a ball straight up, it will rise until it reaches its highest point, where its speed becomes zero before it starts to fall back down. As it descends, it accelerates due to gravity, and when it comes back down, it will reach the same speed it had when thrown, assuming no air resistance. However, in reality, air resistance does play a role, so the ball may come down slightly slower than it went up.
