Question: What is the gravitational potential energy of a mass of 2 kg at a height of 10 m? (g = 9.8 m/s²)

Options:

Correct Answer: 39.2 J

Solution:

PE = mgh = 2 * 9.8 * 10 = 196 J

What is the gravitational potential energy of a mass of 2 kg at a height of 10 m? (g = 9.8 m/s²)

What is the gravitational potential energy of a mass of 2 kg at a height of 10 m? (g = 9.8 m/s²)

Step 1: Identify the formula for gravitational potential energy (PE), which is PE = mgh.
Step 2: Identify the values needed for the formula: mass (m) = 2 kg, height (h) = 10 m, and gravitational acceleration (g) = 9.8 m/s².
Step 3: Substitute the values into the formula: PE = 2 kg * 9.8 m/s² * 10 m.
Step 4: Calculate the multiplication: 2 * 9.8 = 19.6.
Step 5: Now multiply the result by the height: 19.6 * 10 = 196.
Step 6: The gravitational potential energy is 196 Joules (J).
