Question

as a person moves down a zip wire her increase in kinetic energy is less than her decrease in gravitational potential energy explain why

Answer 1

Answer:

-2/9(3/5+2/9)=-2/9×3/5+(-4/4×2/9)

Answer 2

Answer:

This is a classical example of energy conservation.

1. The necessity to preserve energy.
2. Because potential energy is only a function of the body's unstable posture, it decreases as the body moves toward stability; yet, because energy must be conserved, kinetic energy increase as a consequence.

Explanation:

Potential energy:

Potential energy in physics is the energy that an item retains as a result of its position in relation to other objects, internal tensions, electric charge, or other elements.

Kinetic energy:

The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
