Questions & Step-by-Step Solutions
A force of 10 N is applied to move a box 5 m along a horizontal surface. What is the work done by the force? (2021)
Step 1: Identify the force applied to the box, which is 10 N.
Step 2: Identify the distance the box is moved, which is 5 m.
Step 3: Use the formula for work done, which is Work = Force × Distance.
Step 4: Substitute the values into the formula: Work = 10 N × 5 m.
Step 5: Calculate the result: 10 N × 5 m = 50 J.
Step 6: Conclude that the work done by the force is 50 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.
