Why is it impossible to demonstrate perfect conservation of momentum in real life here on Earth?,
There are several reasons why it is impossible to demonstrate perfect conservation of momentum in real life on Earth.
One reason is that in real-world situations, there are often external forces acting on objects that can disrupt the conservation of momentum. These external forces can come from factors such as air resistance, friction, and gravitational forces. These forces can cause the total momentum of a system to change over time, making it difficult to perfectly conserve momentum.
Another reason is that in real-life situations, it is difficult to measure and account for all the tiny and complex interactions between objects in a system. Even small uncertainties in measurements or calculations can lead to deviations from perfect conservation of momentum.
Additionally, the concept of perfect conservation of momentum assumes that there are no energy losses in a system. In reality, some energy is always lost as heat, sound, or other forms of energy, leading to a loss of momentum in the system.
Overall, while conservation of momentum is a fundamental principle in physics, achieving perfect conservation of momentum in real-life situations is practically impossible due to the presence of external forces, measurement uncertainties, and energy losses.
