Why is it difficult to use the law of conservation of energy?

Inelastic collisions do lose energy to heat and vibration. Inelastic collisions actually do conserve energy, but the loss of energy to heat and mechanical vibration is hard to calculate so the math equating energy before and energy after is hard to balance.

What is the difference between conservation of mechanical energy and conservation of energy?

The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.

How would you determine whether to use the conservation of momentum or the conservation of energy for a specific problem?

Conservation of energy can be applied without a problem between the two end states. In general, and answering the question, conservation of momentum is used whenever vectors must be used to describe a dynamic problem.

When we can use conservation of energy?

Conservation of energy is extremely useful when force is conservative, which an be expressed as gradient of potential. The change in kinetic energy is equal to change in potential energy. Potential energy can be calculated using final and initial position independent of path.

How can the law of conservation of momentum be used to solve problems of motion?

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Can conservation of energy be violated?

To sum it up, yes, conservation of energy can be violated, but nature makes sure it is always within the limits of uncertainty. In other words, the energy must be returned, and the books set straight pretty quickly.

Why conservation of energy is important?

Why Is Energy Conservation Important? Energy conservation is incredibly important for several reasons. Along with reducing our reliance on non-renewable energy resources (like fossil fuels), it also helps save you money on energy costs, including utility bills and other energy bills.
