# Is Gravity Impacting Projectile Range Beyond Air Resistance Effects?

• Amateur999
In summary, the conversation discusses the maximum range of an arrow when launched at a 45 degree angle with an initial velocity measured horizontally. It is noted that this range is reduced by air resistance, but also by the decrease in initial velocity caused by the constant propulsive force and gravity, which reduces velocity by approximately 3m/sec. It is mentioned that not all distance loss is due to drag, and the authors are seeking confirmation of this. Additionally, it is mentioned that the loss of speed as the arrow climbs is offset by the gain as it descends, with the help of gravity.

TL;DR Summary
Drag and projectile motion
Calculated maximum range of arrow at 45 degrees with initial velocity measured horizontally is of course reduced by air resistance. BUT initial velocity at 45 is reduced because propulsive force is constant and gravity reduces velocity by about 3m/sec. So not all distance loss is drag. Authors attibute all loss to drag so i need authorative confirmation of this extra factor.

The loss of speed as the arrow climbs is made up for by the gain as it descends and gravity is helping.

Welcome!
Could you explain that part?

## 1. What is gravity?

Gravity is a force that attracts objects with mass towards each other. It is one of the four fundamental forces of nature and is responsible for the motion of planets, stars, and other celestial bodies.

## 2. How does gravity affect projectile range?

Gravity affects projectile range by pulling the object towards the ground as it travels through the air. This downward force causes the projectile to follow a curved path, resulting in a shorter range compared to if there was no gravity present.

## 3. What factors affect projectile range?

The factors that affect projectile range include the initial velocity, angle of launch, air resistance, and gravity. These factors all play a role in determining the distance a projectile will travel.

## 4. How can we calculate projectile range?

The range of a projectile can be calculated using the equation R = (v^2 * sin(2θ)) / g, where R is the range, v is the initial velocity, θ is the angle of launch, and g is the acceleration due to gravity.

## 5. How does air resistance impact projectile range?

Air resistance, also known as drag, can decrease the range of a projectile by slowing it down as it travels through the air. This force is dependent on the shape and size of the object and the density of the air it is moving through.
