Why does a speeding bullet and a fact moving train have so much force?
A speeding bullet and a fast-moving train have a lot of force because of their momentum. Momentum is the product of mass and velocity, so the greater the speed and mass of an object, the more force it has. In the case of a bullet or a train, their high velocity and mass result in a significant amount of force when they collide with another object.
Why does a speeding bullet and a train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.

When a rifle is fired how does the size of the force of the rifle on the bullet compare with the force of the bullet on the rifle how does the acceleration of the rifle compare with that of the bullet?
The force of the rifle on the bullet and the force of the bullet on the rifle are equal in magnitude but opposite in direction, according to Newton's third law of motion. However, the mass of the rifle is much larger than the mass of the bullet, so the acceleration of the rifle is much smaller compared to the acceleration of the bullet.
Why a force of returning of the rifle is smaller than that of the bullet?
The force of the rifle returning back after firing a bullet is smaller than the force on the bullet because the rifle has a larger mass compared to the bullet. According to Newton's third law, force is equal to mass times acceleration, so the force exerted on the rifle is smaller due to the larger mass and slower acceleration compared to the bullet.
How smart is art da dart?
So intelligent a beam of light travels through his brain so fast that it could stop a speeding bullet.
When a rifle fires it accelerates a bullet along the barrel Explain why the rifle must recoil?
For every action, there is an equal and opposite reaction. Now the bullet is light (low mass) so when a certain amount of force pushes the bullet forward and the gun backward at the same time, the bullet moves fast. The gun is heavy (great mass) so it is slower to accellerate rearward. It will never reach even a small fraction of the velocity of the bullet. But since force = mass times velocity squared, there is an equal amount of energy in the bullet and the butt stock of the rifle.
How does the acceleration of the compare with the acceleration of the rifle?
The acceleration of the bullet is greater than the acceleration of the rifle because the bullet has a much smaller mass. Newton's second law, F=ma, states that the acceleration is inversely proportional to mass given the same force, so the smaller mass of the bullet results in a greater acceleration for the same force applied.
How much does a speeding ticket cost in California for doing 47 in a 25?
$380 or so
Why does a gun not move backwards with the same speed the bullets move forward?
Guns do have varying degrees of "kick" when they are fired; the amount of kick depends on the weapon and the type of round being fired. In some cases the kick is substantial and training is needed to avoid injury to the shooter. But guns do have mass, so the gun's own inertia helps to dampen the kick. I think it's not only the bullets or their speed that need to be accounted for. In a sense, a gun is a special case of jet engine at the moment of firing, and all the gasses and particles ignited during the firing act like jet fuel propelling the gun backwards. By Newton's third law of motion, every force exerted by A on B is equally exerted by B on A. So the force that propels the bullet and gases forwards from the gun also propels the gun backwards. The gun does not accelerate to anything like the speed of the bullet because: * Acceleration is inversely proportional to mass, and the gun is much heavier than the bullet. * Your shoulder or hand works against the force from the explosion. Despite the fact that the gun exerts as much force against you as against the bullet, you are not injured. This is chiefy because your region of contact with the weapon is a much greater area than the wrong end of the bullet, distributing the force over a wide area.
When a gun is firesit recoils why?
Because linear momentum is conserved. Before the shot, the momentum of (gun + bullet) is zero, so it has to be zero after the shot. The bullet gains forward momentum when fired, so the gun must gain reverse momentum in order to maintain the zero sum.
What is the difference in grains of bullets for black powder?
The grains of a bullet, be it black powder or not , is the weight of the bullet. Lets say you have a .50 caliber rifle, and fire a 250 grain bullet at a target and hit dead center. Then fire a 300 grain bullet, that bullet will hit slightly lower on the target , but will have more force or stopping power" due to the weight. So the higher the grain the heaver the bullet.
