What is the potential energy of 2.14 kg book that is an bookshelf 1.0m above the floor
The potential energy of an object is given by the equation:
Potential Energy = mass * gravitational acceleration * height
Given:
mass = 2.14 kg
height = 1.0 m
gravitational acceleration is approximately 9.8 m/s^2
Potential Energy = 2.14 kg * 9.8 m/s^2 * 1.0 m
Potential Energy = 20.972 J (rounded to three decimal places)
Therefore, the potential energy of the 2.14 kg book that is 1.0 m above the floor is approximately 20.972 Joules.
To calculate the potential energy of an object, we can use the formula:
Potential Energy = Mass * Gravity * Height
Where:
- Mass is the mass of the object (in kilograms)
- Gravity is the acceleration due to gravity (approximately 9.8 m/s^2 near the surface of the Earth)
- Height is the vertical distance from a reference point (in meters)
In this case, we have a book with a mass of 2.14 kg, and it is placed on a bookshelf 1.0 m above the floor. The acceleration due to gravity is 9.8 m/s^2.
So, applying the formula:
Potential Energy = 2.14 kg * 9.8 m/s^2 * 1.0 m
Potential Energy = 20.972 J (joules)
Therefore, the potential energy of the book on the bookshelf is approximately 20.972 joules.
