Q
Q: An object is lifted vertically 4 m. If the weight of the object is 50 N, how much work is done against gravity?
Solution:
Work done (W) = Force (F) × Distance (d) = 50 N × 4 m = 200 J.
Steps: 6
Show Steps
Step 1: Identify the weight of the object, which is given as 50 N.
Step 2: Identify the distance the object is lifted, which is given as 4 m.
Step 3: Use the formula for work done against gravity, which is Work (W) = Force (F) × Distance (d).
Step 4: Substitute the values into the formula: W = 50 N × 4 m.
Step 5: Calculate the result: 50 N × 4 m = 200 J.
Step 6: Conclude that the work done against gravity is 200 Joules.
