Question: What is the gravitational potential energy of a 2 kg object at a height of 10 m? (2023)

Options:

Correct Answer: 20 J

Solution:

Gravitational potential energy (PE) = mgh = 2 kg × 9.8 m/s² × 10 m = 196 J.

What is the gravitational potential energy of a 2 kg object at a height of 10 m? (2023)

Step 1: Identify the mass of the object. In this case, the mass (m) is 2 kg.
Step 2: Identify the height of the object above the ground. Here, the height (h) is 10 m.
Step 3: Use the acceleration due to gravity. On Earth, this is approximately 9.8 m/s².
Step 4: Use the formula for gravitational potential energy (PE), which is PE = mgh.
Step 5: Substitute the values into the formula: PE = 2 kg × 9.8 m/s² × 10 m.
Step 6: Calculate the result: 2 × 9.8 × 10 = 196 J.
Step 7: Conclude that the gravitational potential energy of the object is 196 Joules.
