Question

Name two of the four common boundary conditions we set when discussing gravitational potential energy?

Answer 1

Two common boundary conditions when discussing gravitational potential energy are zero potential energy at a convenient point and constant potential energy near Earth's surface.

Step-by-step explanation:

When discussing gravitational potential energy, two common boundary conditions that are often set include:

1. Zero potential energy at a convenient point: In this case, a specific point is chosen as the reference level where the potential energy is set to zero. This makes it easier to calculate potential energy differences.
2. Constant potential energy near Earth's surface: Near the surface of the Earth, the potential energy due to gravity is considered to be constant. This allows for simplified calculations.
