What is the kinetic energy of the bullet?
Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
What is kinetic energy derive an expression for the kinetic energy of an object?
Suppose a body of mass m is moving with velocity v. It is brought to rest by applying a retarding force F. Suppose it traverses a distance s before coming to rest. Kinetic energy of body, KE = Work done by retarding force to stop it.
What type of energy conversion took place when a bullet was fired?
A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat.
What kind of energy does a bullet fired from the gun possess How is this energy stored?
kinetic energy
When a bullet is fired from a gun, its potential energy is converted into kinetic energy. When a bullet fired the chemical energy is in form of potential energy is converted in kinetic energy and heat thereby moving bullet out of the barrel. The sum of potential and Kinetic energy is known as Mechanical energy.
How is kinetic energy calculated?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
How is kinetic energy stored?
Potential energy Kinetic energy can be stored. If we drop the object from the shelf or release the spring, that potential energy is converted back into kinetic energy. Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic.
