Q
Q: A 10 kg object is lifted to a height of 2 m. What is the work done against gravity? (g = 9.8 m/s²)
Solution:
Work done (W) = m × g × h = 10 kg × 9.8 m/s² × 2 m = 196 J.
Steps: 6
Show Steps
Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
Step 2: Identify the height to which the object is lifted. Here, the height (h) is 2 m.
Step 3: Identify the acceleration due to gravity. It is given as g = 9.8 m/s².
Step 4: Use the formula for work done against gravity: Work (W) = mass (m) × gravity (g) × height (h).
Step 5: Substitute the values into the formula: W = 10 kg × 9.8 m/s² × 2 m.
Step 6: Calculate the result: W = 10 × 9.8 × 2 = 196 J.
