Question: When a rifle fires a bullet which object has greater acceleration?

Thus for same force, the smaller mass object has greater acceleration. Thus the acceleration of the bullet is greater than that of gun.

When a rifle fires a bullet which has the larger acceleration the bullet or the rifle justify your answer using the the second and third law of motion?

“When a rifle shoots a bullet, Newton’s Third Law says that the force that the rifle exerts on the bullet is exactly the same size as the force that the bullet exerts on the rifle – yet the bullet gets a much greater acceleration than the rifle.

Which has a greater acceleration the gun or the bullet?

The force on the rifle equals the force on the bullet. Yet, acceleration depends on both force and mass. The bullet has a greater acceleration due to the fact that it has a smaller mass. Remember: acceleration and mass are inversely proportional.

Why do the bullet and gun have very different accelerations?

They have different accelerations because of their masses. According to Newton’s Second Law, an objects acceleration is inversely proportional to its mass. … In the same way, the less massive object, being the bullet, will have a higher acceleration.

When a bullet is fired from a gun the acceleration of the gun is?

When a gun is fired ,it exerts a forward force on the bullet. The bullet exerts an equal and opposite force on the gun. This results in the recoil of gun. Since the gun has a much greater mass than the bullet,the acceleration of the gun is much less than the acceleration of the bullet.

What are the 3 laws of motion?

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.

Which is more important in winning in a tug of war?

There are 6 forces exerted. Which is most important in winning in a tug-of-war; pulling harder on the rope, or pushing harder on the floor? Pushing harder on the floor. … The paper isn’t capable of exerting a reaction force.

Why does a gun recoil backwards when fired?

When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. … The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.

Why is the acceleration of the gun much less than the acceleration of bullet when the gun is fired?

Answer. ▶️ Because, the mass of the gun is more and the mass of the bullet is less , exert pressure to move or accelerate . As we know that every object has an equal and opposite reaction , so if the bullet moves forward the gun will move backward a bit .

Is the recoil of a gun the same force as the bullet?

Both the bullet and the gun experience the same force but in opposite directions. These two forces are equal and opposite of each other. This opposite force manifests itself as recoil, which is where the gun pushes back whenever it is fired.

What forces act on a bullet?

Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag.

How much force does a bullet have in Newtons?

The average force exerted on the bullet is 304 Newtons.

How does Dr Hewitt break the piece of wood?

How is Dr. Hewitt able to break a piece of wood in his demonstration? He moves his hand very quickly.

Can a gun actually backfire?

But, no, in the real world guns do not backfire. If, however, a gun has its bore obstructed, is improperly loaded, or otherwise malfunctions, it can explode, sending hell hot gases and potentially lethal shards of metal back towards the shooter.

What is the average acceleration of a bullet?

With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 105 m/s2. 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.

Does a bullet speed up after leaving the barrel?

Originally Answered: Does a bullet accelerate after leaving the barrel? No. It accelerates inside the barrel, but as soon as it exits the muzzle the energy pushing it drops to zero. The graph below shows the curve of pressure increasing in the barrel and then dropping to zero as the bullet exits.
