Work Calculation: A Teacher Lifted a 10 N Box
Did the teacher do any work when she lifted a 10 N box?
Based on the given data, did the teacher do any work? Calculate and explain your answer.
Answer:
Yes, the teacher did work when she lifted the 10 N box. Work is defined as force applied over a distance, and in this case, the teacher exerted a force to lift the box against the force of gravity.
To calculate the work done by the teacher, we can use the formula:
Work = Force x Distance
Given that the force applied by the teacher is 10 N and assuming she lifted the box a certain distance, we can calculate the work done. Let's say the distance lifted is 1 meter:
Work = 10 N x 1 m = 10 Joules
Therefore, the teacher did 10 Joules of work when she lifted the 10 N box.
