# Gravity's Impact: Comparing Ball A and B

• zizodev
In summary, the question is which of two balls, one filled with air and the other filled with water, will hit the ground first when dropped from a height of 100 feet. The suggested answer is that the ball filled with water will hit the ground first due to its higher density. However, a quantitative reason is needed to support this answer.

## Homework Statement

consider two balls of exactly the same size and material.
Ball A is filled with air and ball B is filled with water.if dropped from a height of 100 feet,which will hit the ground first?

U=mgh.

## The Attempt at a Solution

i suggest the ball B will hit the ground first because the water is more denser than air.

Nice hunch, but can you supply a quantitative reason?

yes PeterO we didn't know how that air in the ball is it in high pressor or not :)

## 1. How does gravity affect the trajectory of Ball A and B?

The force of gravity affects the trajectory of both Ball A and B. As they are released from the same height, they will follow a similar path until they reach the ground. However, the mass and shape of the balls can also impact the trajectory.

## 2. Why does Ball A reach the ground faster than Ball B?

Ball A reaches the ground faster than Ball B because it has a greater mass. According to Newton's Second Law of Motion, an object with a greater mass will experience a greater force due to gravity, causing it to accelerate faster.

## 3. Does the surface of the balls affect their impact due to gravity?

Yes, the surface of the balls can affect their impact due to gravity. A smoother surface may experience less air resistance, allowing it to fall faster. Additionally, the surface material can affect the amount of force that is absorbed upon impact with the ground.

## 4. How does the location of the experiment affect the impact of gravity on the balls?

The location of the experiment can affect the impact of gravity on the balls due to factors such as altitude and the shape of the Earth. The force of gravity can vary slightly depending on these factors, which can impact the trajectory and speed of the balls as they fall.

## 5. Can the height from which the balls are released affect their impact due to gravity?

Yes, the height from which the balls are released can affect their impact due to gravity. The higher the height, the longer the balls have to accelerate before reaching the ground, resulting in a higher impact force. Additionally, the height can also impact the potential energy of the balls, which can affect their speed and trajectory.
