Introduction
In physics, the potential energy of an object is the energy it possesses due to its position or configuration. In this article, we will calculate the potential energy of a 7.00 kg bowling ball held 2.00 m above the ground. We will use the formula for potential energy, which is given by:
PE = mgh
where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.
Calculating Potential Energy
To calculate the potential energy of the bowling ball, we need to plug in the values of m, g, and h into the formula. The mass of the bowling ball is given as 7.00 kg, the acceleration due to gravity is given as 9.80 m/s^2, and the height of the bowling ball above the ground is given as 2.00 m.
PE = mgh PE = (7.00 kg) * (9.80 m/s^2) * (2.00 m) PE = 137.6 J
Rounding to Significant Figures
Since the answer choices are given in one decimal place, we will round our answer to one decimal place. Therefore, the potential energy of the bowling ball is approximately 137 J.
Conclusion
In conclusion, the potential energy of a 7.00 kg bowling ball held 2.00 m above the ground is approximately 137 J. This is the energy the bowling ball possesses due to its position, and it can be calculated using the formula PE = mgh.
Answer
The correct answer is B. 137 J.
Discussion
The potential energy of an object is an important concept in physics, and it is used to describe the energy an object possesses due to its position or configuration. In this article, we calculated the potential energy of a 7.00 kg bowling ball held 2.00 m above the ground using the formula PE = mgh. The result was approximately 137 J, which is the energy the bowling ball possesses due to its position.

A 7.00 kg Bowling Ball's Potential Energy: Q&A =====================================================
Introduction
In our previous article, we calculated the potential energy of a 7.00 kg bowling ball held 2.00 m above the ground using the formula PE = mgh. In this article, we will answer some frequently asked questions related to potential energy and the calculation of the bowling ball's potential energy.
Q: What is potential energy?
A: Potential energy is the energy an object possesses due to its position or configuration. It is a measure of the energy an object has because of its height, position, or state.
Q: What is the formula for potential energy?
A: The formula for potential energy is PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.
Q: What is the acceleration due to gravity?
A: The acceleration due to gravity is 9.80 m/s^2 on Earth's surface. This value may vary slightly depending on the location and the presence of other objects.
Q: How do I calculate the potential energy of an object?
A: To calculate the potential energy of an object, you need to know the mass of the object, the acceleration due to gravity, and the height of the object above the ground. You can then plug these values into the formula PE = mgh to calculate the potential energy.
Q: What is the unit of potential energy?
A: The unit of potential energy is joules (J).
Q: Can potential energy be negative?
A: Yes, potential energy can be negative. This occurs when the object is below the reference level, such as when an object is submerged in water.
Q: What is the relationship between potential energy and kinetic energy?
A: Potential energy and kinetic energy are related by the law of conservation of energy. As an object falls from a height, its potential energy is converted into kinetic energy.
Q: Can potential energy be converted into other forms of energy?
A: Yes, potential energy can be converted into other forms of energy, such as kinetic energy, thermal energy, or electrical energy.
Q: What is the significance of potential energy in real-life situations?
A: Potential energy is significant in real-life situations, such as in the design of buildings, bridges, and other structures. It is also important in the study of energy conversion and the development of new energy technologies.
Conclusion
In conclusion, potential energy is an important concept in physics that describes the energy an object possesses due to its position or configuration. We have answered some frequently asked questions related to potential energy and the calculation of the bowling ball's potential energy. We hope this article has provided a better understanding of potential energy and its significance in real-life situations.
