Question
Which object has the most gravitational potential energy?A.A 20 kg suitcase at a height of 1.5 mB.A 30 kg suitcase at a height of 2 mC.A 20 kg suitcase at a height of 2 mD.A 30 kg suitcase at a height of 1.5 m
Solution
The gravitational potential energy of an object can be calculated using the formula:
Potential Energy (PE) = mass (m) * gravity (g) * height (h)
Where:
- mass is measured in kilograms (kg)
- gravity is approximately 9.8 m/s² on Earth
- height is measured in meters (m)
Let's calculate the potential energy for each object:
A. PE = 20 kg * 9.8 m/s² * 1.5 m = 294 Joules B. PE = 30 kg * 9.8 m/s² * 2 m = 588 Joules C. PE = 20 kg * 9.8 m/s² * 2 m = 392 Joules D. PE = 30 kg * 9.8 m/s² * 1.5 m = 441 Joules
So, the object with the most gravitational potential energy is B. A 30 kg suitcase at a height of 2 m.
