# Why do the bullet and gun have very different accelerations?

## Why do the bullet and gun have very different accelerations?

If the forces that act on a bullet and the recoiling gun from which it is fired are equal in magnitude, why do the bullet and gun have very different accelerations? They have very different masses. According to Newton’s 2nd law of motion, the acceleration of an object is inversely proportional to its mass.

## How does the force of the rifle compare with the force on the bullet and why?

Part A: How does the force on the rifle compare with the force on the bullet, and why? The magnitude of the force on the rifle is equal to the magnitude of force on the bullet and the forces are in the opposite direction, because for every action there is an equal and opposite reaction.

How do their accelerations compare?

When they pull on the rope, they each slide toward each other. How do their accelerations compare and how far does each person slide before they meet? The force on each will be the same so they will always have the same acceleration — and, because of that, the same velocity and they will move the same distance.

### How does the magnitude of acceleration of the rifle compare?

The magnitude of acceleration of the rifle is greater than the magnitude of acceleration of the bullet. Even though they experience the same magnitude of force, the mass of the rifle is greater, and so the rifle will experience a greater acceleration than the bullet.

### How does bullet accelerate?

‘Muzzle velocity’ depends on the type of gun and bullet, with high-velocity rifles firing bullets at much higher speeds than small handguns. But the explosive charge that propels a bullet out of a gun will typically produce accelerations of over 100,000 times that due to gravity.

Is the acceleration of the recoiling rifle greater or smaller than the acceleration of the bullet?

Newton’s Third Law : Example Question #4 Consistent with Newton’s third law, which states that every force has an equal and opposite reaction, the force on the rifle is equal to the force on the bulet. However, the rifle has a larger mass, so the magnitude of its acceleration is less than that of the bullet.

#### Is the force that the bullet exerts on the rifle the same amount of force that the rifle exerts on the bullet?

When a rifle is fired, the force that the rifle exerts on the bullet (“action” force) is exactly the same size as the force the bullet exerts on the rifle (“reaction” force). Since the bullet has a small mass, it gets a large acceleration (Abullet = Fbullet/mbullet).

#### What does acceleration measure?

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. In everyday English, the word acceleration is often used to describe a state of increasing speed. Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction.

What is accelerating uniformly?

Translation: If an object’s speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration. uniform acceleration.

## Is the magnitude of force is the rifle equal to the magnitude force of the bullet?

Correct answer: Consistent with Newton’s third law, which states that every force has an equal and opposite reaction, the force on the rifle is equal to the force on the bulet. However, the rifle has a larger mass, so the magnitude of its acceleration is less than that of the bullet.

## How many Gs is a bullet?

Standard bullet weight is 7.0 grams (108 gr) to 8.3 grams (128 gr).

Which bullet is the fastest?

The . 220 Swift remains the fastest commercial cartridge in the world, with a published velocity of 1,422 m/s (4,665 ft/s) using a 1.9 grams (29 gr) bullet and 2.7 grams (42 gr) of 3031 powder.

### What makes a bullet have a lower acceleration?

The acceleration of a bullet depends largely on the gun from which it is fired, along with the intent of the user. Pistol bullets generally feature a lower acceleration than rifles or machine guns.

### What is the acceleration of a 127 mm bullet?

With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 10 5 m/s 2. The acceleration of a bullet depends largely on the gun from which it is fired, along with the intent of the user.

What is the muzzle velocity of a 9 mm Parabellum Bullet?

Since acceleration is the desired value, the derived formula is this: When fired from a Beretta 92S, the standard issue US Army pistol, a 9 mm Parabellum bullet has a muzzle velocity of 335 m/s. With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 10 5 m/s 2.

#### What causes a bullet to move forward in a gun?

This causes a rapid expansion of gas, which forces the bullet forward and ejects the casing. Contrary to popular belief, guns are not loaded with bullets, but cartridges, and they fire bullets (since bullets are a more common term and the actual objects responsible for harm, they receive the recognition).
