Understanding the Formula
The formula for gravitational potential energy is:
GPE = mgh
Where:
* m is the mass of the object (in kilograms)
* g is the acceleration due to gravity (approximately 9.8 m/s²)
* h is the height above the reference point (in meters)
Applying the Formula
1. Mass (m): 2 kg
2. Acceleration due to gravity (g): 9.8 m/s²
3. Height (h): 5 m
Calculation:
GPE = (2 kg) * (9.8 m/s²) * (5 m)
GPE = 98 Joules (J)
Answer: The gravitational potential energy of the 2 kg ball 5 meters above the floor is 98 Joules.
