Questions & Step-by-Step Solutions
An object is lifted vertically 4 m. If the weight of the object is 50 N, how much work is done against gravity?
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.
Work Done Against Gravity – Work is calculated as the product of the force applied and the distance moved in the direction of the force. In this case, it involves lifting an object against the gravitational force.
