Question: What is the potential energy of an object of mass 2 kg at a height of 10 m? (g = 9.8 m/s²) (2022)

Options:

Correct Answer: 196 J

Exam Year: 2022

Solution:

Potential energy (PE) is calculated using the formula PE = mgh. Here, PE = 2 kg × 9.8 m/s² × 10 m = 196 J.

What is the potential energy of an object of mass 2 kg at a height of 10 m? (g = 9.8 m/s²) (2022)

What is the potential energy of an object of mass 2 kg at a height of 10 m? (g = 9.8 m/s²) (2022)

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: Identify the acceleration due to gravity. This value (g) is given as 9.8 m/s².
Step 4: Use the formula for 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.
Step 7: Conclude that the potential energy of the object is 196 Joules (J).
