If a force of 15 N moves an object 3 m in the direction of the force, what is the work done? (2022)
Step 1: Identify the force applied to the object, which is 15 N (Newtons).
Step 2: Identify the distance the object moves in the direction of the force, which 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 in the direction of the force.
Units of Measurement – Understanding the units of force (Newtons) and distance (meters) is crucial for calculating work (Joules).
