In a perfect world without air resistance, the top of the swing would have the most potential energy, but the least amount of kinetic energy. As the pendulum falls down, it gains more kinetic energy as it travels faster due to gravitational acceleration but loses more potential energy as it loses height. The total amount of energy in the system (the sum of kinetic and potential energy) stays the same.
A)→ Haze surrounding a nucleus
B)→ Created by solar wind.
C)→ Hypothetical sphere around the solar system
The orbit gets larger when the mass of the sun is reduced to 75,000.
It is the gravitational force pulling on something
