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

Options:

Correct Answer: 100 J

Solution:

The gravitational potential energy is calculated using the formula U = mgh = 10 kg * 9.8 m/s² * 5 m = 490 J.

What is the gravitational potential energy of a 10 kg mass at a height of 5 m above the ground?

What is the gravitational potential energy of a 10 kg mass at a height of 5 m above the ground?

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