## How do you solve for gravitational potential energy?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

**What is the example of gravitational potential energy?**

Examples of Gravitational Potential Energy For example, a book on a high bookshelf has higher potential energy than a book on the bottom shelf because it has farther to fall. Other examples of items with gravitational potential energy include: A raised weight. Water that is behind a dam.

**At which position does the child on the swing have the most gravitational potential energy *?**

The girl on the swing has the most potential energy just as she is being pushed because she is at the highest position at this point.

### Which object has the greatest gravitational potential energy?

The heaviest of 2 objects at the same height has the greatest gravitational potential energy.

**What two factors affect how much gravitational potential energy an object has?**

Gravitational Potential Energy is determined by three factors: mass, gravity, and height.

**What units are used for gravitational potential energy?**

gravitational potential energy is measured in joules (J) mass is measured in kilograms (kg)

## Can gravitational potential energy negative?

The gravitational potential energy could even be negative if the object were to pass below the zero point. This doesn’t present a problem, though; we just have to be sure that the same zero point is used consistently in the calculation.

**In which case is there an increase in gravitational potential energy *?**

An object’s gravitational potential is due to its position relative to the surroundings within the Earth-object system. The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system.

**How is gravitational potential energy related to the mass of the object?**

Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.

### How does mass affect gravitational potential energy?

The mass of the object- The more mass an object has, the more gravitational potential energy it will have if it is given a position with the potential to fall. The distance it is from the surface of the Earth- The farther an object can fall, the more gravitational potential energy it will have.

**What are the variables required to find gravitational potential energy?**

The factors that affect an object’s gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.

**Why do books on a shelf have gravitational potential energy?**

The gravitational potential energy will increase as the mass on it will increase. As mass is one of the factors for gravitational potential energy, the number of books effectively increases the mass of the bookshelf, thereby increasing its potential energy.
