Exergy and Energy. When the sign of potential energy is negative this is called exergy and indicates that energy comes out, thus exergy. This is the case when opposite charges are involved, the potential energy is negative and this configuration emits energy. When the charges are the same the sign is positive and energy is absorbed in this configuration.
Newton discovered that gravity is exergy, emits energy as the masses attract each other. Taking the center at one of the masses, this accounts for the center seeking behavior of gravity.

What is the effect of centre of gravity on stability of the body?
The lower the center of gravity of an object, the more stable it is. This is because a low center of gravity makes it harder for the object to tip over. Objects with a higher center of gravity are more prone to tipping or rolling over due to imbalance.
What makes things fall when you drop them?
Things fall when you drop them because of gravity. Gravity is the force that pulls objects toward each other. When you release an object, gravity pulls it toward the center of the Earth, causing it to fall.
Why is weight affected by gravity?
Weight is affected by gravity because weight is the force exerted on an object due to gravity pulling it towards the center of the Earth. The strength of gravity determines the weight of an object; the stronger the gravitational force, the heavier the object will feel.
When an object is said to be heavy what are the two things being considered?
When an object is said to be heavy, two things being considered are its mass and the force of gravity acting on it. The mass of an object is the amount of matter it contains, while the force of gravity pulling it towards the Earth's center contributes to its weight.
Why do things randomly fall?
Objects fall due to the force of gravity, which pulls them towards the center of the Earth. When an object is not supported or balanced, gravity causes it to fall towards the ground.

How does gravity make things fall?
The weight of the object causes gravity to take the object falling
What is a force of gravity on an object?
The force of gravity on an object is the downward pull exerted by the Earth's mass on the object. It is directly proportional to the mass of the object and the mass of the Earth, and inversely proportional to the square of the distance between the object and the center of the Earth.
What 2 things can happen with a balanced object?
A balanced object will remain stationary if placed on a flat surface, demonstrating stability. If the object is disturbed, it will return to its original position due to its center of gravity being at its equilibrium point.
What strong force pulls things towards the center of earth?
Gravity.
Why is the object thrown up always comes down?
The object comes back down after being thrown up because of gravity, a force that attracts things towards each other. When an object is thrown up, the force of gravity eventually overcomes the initial momentum and pulls the object back towards the center of the Earth.
What things affects the gravity you feel?
The gravity you feel is primarily affected by your distance from the center of a massive object, such as Earth. Gravity is weaker at higher altitudes and stronger closer to the surface due to the distribution of mass. Factors like the mass of the object and your own mass also play a role in determining the gravity you experience.
What is reason for things falling down?
Objects fall down due to the force of gravity. Gravity is a fundamental force that pulls objects towards the center of the Earth. When an object is unsupported, gravity causes it to accelerate downwards until it reaches the ground.
