How do you measure kinetic energy?
To calculate the kinetic energy, multiply the mass times the velocity squared and divide by 2. (Mass in kilograms, speed in meters/sec, yields energy in joules.) The equation is KE= 1/2 (mv2) Kinetic Energy= one-half (mass times velocity squared)
When a bulltet is fired from a rifle it is the bullet which causes damage but nit recoiling gun answer you according to momentum or third law of motion?
I believe that you are asking if the bullet is what causes so much damage to something it strikes, then why doesn't the shooter suffer an equivalent amount of damage? The answer does have a lot to do with momentum. I think that there may be some confusion between the conservation of momentum, which is the essence of Newton's Third Law, and the definition of kinetic energy.The magnitude of the momentum of the bullet just as it leaves the barrel of a gun is equal to, but in the opposite direction of, the magnitude of the momentum of the gun plus any momentum imparted to the shooter's body.I apologize if you already know much of my answer, but I will show the equations for momentum and kinetic energy. Momentum is a vector because it has both direction and magnitude, and the equation for momentum is p = m•v, where p is momentum, m is the object's mass in kg, and v is the object's velocity in meters/sec. (The vector quantities are in bold. I'm using the units prescribed in the kms system.)The reason the bullet causes damage to whatever it strikes is due to the bullet's kinetic energy, which is defined by the equation Ek=1/2mv2, where m is the mass of the bullet in kg and v is the bullet's speed in meters/sec. The fact that the kinetic energy is proportional to the square of the velocity is of paramount importance. Just like momentum, energy is also conserved. Energy (or the combination of energy and mass in the cases of nuclear fission and nuclear fission) is never lost; it can only change forms. All the energy released from every bullet, bomb, and shell used in World War II, or any other war, is still present somewhere in the universe, although almost all of it is still present on the Earth in some form. Thus, the kinetic energy of a bullet fired from a gun is initially exactly equal to the kinetic energy imparted to the backward-moving gun, the gun's report, the flash of light from the muzzle, the heating of the gun's receiver, chamber, and barrel, the heating of the bullet and of whatever it hit, the frictional heating of the air through which the bullet passed, and the energy expended in damaging what the bullet struck.The reason the shooter of the gun is not severely damaged (although anyone who has ever fired a very powerful rifle such as a 375 H&H or a 460 Wetherby Magnum might disagree) is because the energy of the bullet is proportional to the square of the velocity. Because the mass of the gun is so much greater than the mass of the bullet, the rearward velocity of the gun is very much less than the velocity of the bullet such that the gun cannot cause significant damage to the shooter.
What is the unit of measurement of gun firepower?
The unit of measurement for gun firepower is typically given in Joules or foot-pounds. This measurement represents the energy of the projectile when it is fired from the gun.
An object with zero momentum must have zero potential energy?
No. If the momentum of a pair of objects is zero sitll they can have kinetic energy.For example, in the case of bullet and gun, before firing the bullet the total momentum is zero and according to the law of conservation of momentum, the total momentum after firing the bullet will also be zero. But still they both will have kinetic energy.
How do you calculate the recoil velocity?
(equal and opposite reaction) if a gun recoil kinetic energy (ke) is same as bullet kinetic energy then : say 0.02 kilogram slug @ 1 000 m/s the ke 0.5*m*v^2 = 10 000 joules (j) say gun @ 1 kg then : 10 000 j = 1 * v^2 , then v = sq root 10 000 = 100 m/s actually, last line should read: say gun @ 1kg then : 10 000 j = (1 * v^2)/2, then v=sq root 20 000=141m/s
Which energy is possessed by bullet released from a gun?
Kinetic, potential, and heat.
Is a loaded gun an example of kinetic energy?
No, a loaded gun is an example of potential energy, specifically stored mechanical energy due to its position. Once fired, the bullet will exhibit kinetic energy as it moves through space.
What are the energy transformations when a gun is fired?
There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.
How do you tell the kinetic energy of a ball when it leaves a gun?
To calculate the kinetic energy of a ball leaving a gun, you can use the formula KE = 0.5 * m * v^2, where m is the mass of the ball and v is its velocity. By measuring or determining the mass of the ball and the velocity at which it leaves the gun, you can calculate its kinetic energy.
What is the chemical reaction involve in the explosion of fireworks?
Gun powder and kinetic energy
When a bullet leaves a gun the bullet has what type of energy?
The bullet has a great deal of kinetic energy, because of its high speed. It also has a little bit of potential energy relative to the ground, because of its height above the ground.
Which has more energy the bullet or the recoiling gun?
Although their linear momenta are equal, their potential, kinetic, and heat energies are different. The gun has more heat. Regarding potential energy, it can vary. But if the shot is anywhere near horizontal and the shooter doesn't drop the gun, then the recoiling gun has more gravitational potential energy at any time after the shot. The fired bullet has more kinetic energy.
When a bullet is fired from a gun what happens to the energy released?
When a bullet is fired from a gun, the energy stored in the gunpowder is converted into kinetic energy that propels the bullet forward. The bullet carries this kinetic energy as it travels through the air until it hits a target or loses its energy through friction and air resistance.
What energy transformations occur when a gun is shot?
When a gun is shot, chemical energy stored in the gunpowder is rapidly converted into thermal energy through combustion. This thermal energy then rapidly expands gases inside the gun barrel, leading to the generation of mechanical energy propelling the bullet forward.
What type of energy store is stored in a gun bullet?
While it is moving, it has kinetic energy. Before it is shot, it has chemical energy - that's what causes the explosion.
Where is the most kinetic energy?
The most kinetic energy is typically found in moving objects that have a high velocity and a large mass. For example, a speeding car on a highway or a fast-moving bullet fired from a gun would have a significant amount of kinetic energy due to their velocity and mass.
What is the kinetic energy of a ball if a child does 5.0J of work on a spring while loading the ball into a spring loaded gun?
The work done by the child on the spring is equal to the potential energy stored in the spring. If all of this potential energy is then transferred to the ball as kinetic energy, the kinetic energy of the ball would also be 5.0 J.
