how is kinetic energy not conserved in inelastic collisions?
72742
An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else.

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. ... The total system momentum is conserved.

In an elastic collision, mechanical energy is conserved – the sum of the mechanical energies of the colliding objects is the same before and after the collision. After an inelastic collision, however, the mechanical energy of the system will have changed.

The kinetic energy would be KE= ½mv2,where m is the mass of the pendulum, and v is the speed of the pendulum. At its highest point (Point A) the pendulum is momentarily motionless. All of the energy in the pendulum is gravitational potential energy and there is no kinetic energy.

Momentum is simply transferred from one object to the other object. Put another way, it could be said that when a collision occurs between two objects in an isolated system, the sum of the momentum of the two objects before the collision is equal to the sum of the momentum of the two objects after the collision.

These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

In an elastic collision, total kinetic energy and the total momentum before and after the collision are the same. In an inelastic collision, some of the energy gets converted into other forms of energy such as sound energy or thermal energy. The forces featured by an elastic collision are conservative in nature.

Mechanical energy is conserved so long as we ignore air resistance, friction, etc. ... Energy is "lost" to friction in the sense that it is not converted between potential and kinetic energy but rather into heat energy, which we cannot put back into the object.

If there is no friction then energy is conserved. There are two parts in this case, potential energy and kinetic energy. The object starts out with no kinetic energy and potential energy of PE = mgh where m is the mass, g is acceleration due to gravity and h is its initial height above the ground.

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.

An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. ... Momentum is conserved in inelastic collisions, but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.

Free Fall and Conservation of Energy. ... As it falls and loses GPE, its kinetic energy (KE) increases so that its total mechanical energy (TME) remains constant.

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

Which of these is the most accurate statement about momentum in a collision between two objects? Momentum is only conserved if the colliding objects bounce apart.

An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). ... A collision in which the objects stick together is sometimes called “perfectly inelastic.” An inelastic one-dimensional two-object collision. Momentum is conserved, but internal kinetic energy is not conserved.

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.
