Question: What is the gravitational potential energy of a 5 kg object at a height of 10 m?

Options:

Correct Answer: 100 J

Solution:

Gravitational potential energy (PE) = m * g * h = 5 kg * 9.8 m/s² * 10 m = 490 J.

What is the gravitational potential energy of a 5 kg object at a height of 10 m?

What is the gravitational potential energy of a 5 kg object at a height of 10 m?

Step 1: Identify the mass of the object. In this case, the mass (m) is 5 kg.
Step 2: Identify the height of the object above the ground. Here, the height (h) is 10 m.
Step 3: Know the acceleration due to gravity (g). On Earth, g is approximately 9.8 m/s².
Step 4: Use the formula for gravitational potential energy (PE), which is PE = m * g * h.
Step 5: Substitute the values into the formula: PE = 5 kg * 9.8 m/s² * 10 m.
Step 6: Calculate the result: 5 * 9.8 * 10 = 490 J.
Step 7: Conclude that the gravitational potential energy of the object is 490 Joules.
