Questions & Step-by-Step Solutions
If a force of 15 N is applied to move an object 4 m in the direction of the force, what is the work done?
Step 1: Identify the force applied to the object. 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 4 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 × 4 m.
Step 5: Calculate the result: 15 × 4 = 60.
Step 6: State the final answer: The work done is 60 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 in the direction of the force.
Units of Work – Work is measured in joules (J), where 1 joule is equivalent to 1 newton meter (1 J = 1 N·m).
