If a 2 kg object is lifted to a height of 3 m, what is the work done against gravity? (Use g = 9.8 m/s²) (2023)

If a 2 kg object is lifted to a height of 3 m, what is the work done against gravity? (Use g = 9.8 m/s²) (2023)

Step 1: Identify the mass of the object. In this case, the mass (m) is 2 kg.
Step 2: Identify the height to which the object is lifted. Here, the height (h) is 3 m.
Step 3: Identify the acceleration due to gravity. We use g = 9.8 m/s².
Step 4: Use the formula for work done against gravity, which is Work = mgh.
Step 5: Substitute the values into the formula: Work = 2 kg × 9.8 m/s² × 3 m.
Step 6: Calculate the result: 2 × 9.8 × 3 = 58.8 J.
Step 7: Conclude that the work done against gravity is 58.8 Joules.
