Is it true or wrong to say that, a ball will land at the same time if you drop it straight down from the top of a tower or if you throw it out horizontally? Either yes or no explain it with a solid reason.   

Solution:

No, it is not true to say that a ball will land at the same time whether you drop it straight down from the top of a tower or if you throw it out horizontally. The reason for this is because of the horizontal component of the ball's velocity when it is thrown.

When you throw the ball horizontally, it has both a horizontal and vertical component to its velocity. The horizontal component keeps the ball moving forward, while the vertical component determines how high the ball goes before it begins to fall back down.

However, when you drop the ball straight down from the top of the tower, it only has a vertical component to its velocity. The ball falls straight down, accelerating at a rate of 9.8 meters per second squared due to gravity.

Therefore, because the ball thrown horizontally has an initial horizontal velocity that the ball dropped straight down does not, it will take longer for the horizontally thrown ball to reach the ground. The ball dropped straight down will reach the ground first.
