Questions & Step-by-Step Solutions
A 3 kg object is pushed with a force of 12 N over a distance of 4 m. What is the work done on the object?
Step 1: Identify the force applied to the object. In this case, the force is 12 Newtons (N).
Step 2: Identify the distance over which the object is pushed. Here, the distance is 4 meters (m).
Step 3: Use the formula for work done, which is Work (W) = Force (F) × Distance (d).
Step 4: Substitute the values into the formula: W = 12 N × 4 m.
Step 5: Calculate the result: 12 N × 4 m = 48 Joules (J).
Step 6: Conclude that the work done on the object is 48 J.
Work – Work is defined as the product of the force applied to an object and the distance over which that force is applied, in the direction of the force.
Units of Work – Work is measured in joules (J), where 1 joule is equivalent to 1 newton-meter.
