Questions & Step-by-Step Solutions
How much work is done when a force of 15 N moves an object 3 m in the direction of the force?
Step 1: Identify the force applied. In this case, the force is 15 N (Newtons).
Step 2: Identify the distance the object is moved in the direction of the force. Here, the distance is 3 m (meters).
Step 3: Use the formula for work done, which is Work = Force × Distance.
Step 4: Substitute the values into the formula: Work = 15 N × 3 m.
Step 5: Calculate the result: 15 × 3 = 45.
Step 6: State the final answer: The work done is 45 J (Joules).
Work – Work is defined as the product of the force applied to an object and the distance over which that force is applied, specifically when the force and movement are in the same direction.
Units of Work – Work is measured in joules (J), where 1 joule is equivalent to 1 newton meter (1 J = 1 N·m).
