What is the Gravitational Potential Energy (GPE) of a 3 kg Block 5 m Above the Floor?

Gravitational potential energy (GPE) is the energy possessed by an object due to its position within a gravitational field. In this article, we will calculate the GPE of a 3 kg block located 5 m above the floor.

Understanding Gravitational Potential Energy (GPE)

• Definition: GPE is the energy stored in an object due to its position in a gravitational field.
• Formula: GPE = mgh, where:
• m is the mass of the object (in kilograms)
• g is the acceleration due to gravity (approximately 9.8 m/s² on Earth)
• h is the height of the object above the reference point (in meters)

Calculating the GPE of a 3 kg Block 5 m Above the Floor

Given:

• Mass (m) = 3 kg
• Height (h) = 5 m

Steps:

1. Identify the Acceleration Due to Gravity (g): On Earth, g is approximately 9.8 m/s².
2. Plug In the Values: Substitute the given values into the GPE formula: GPE = mgh
3. Calculate: GPE = (3 kg) x (9.8 m/s²) x (5 m) = 147 J

Therefore, the GPE of a 3 kg block located 5 m above the floor is 147 J.

Conclusion

The GPE of an object is a fundamental concept in physics. Understanding the concept of GPE is essential for analyzing various phenomena involving objects in gravitational fields. In this article, we calculated the GPE of a 3 kg block located 5 m above the floor, demonstrating the application of the GPE formula to a practical scenario.
