2.which would take more work: lifting a 4 n box 0.5 m or a 1 n box 4 m? explain your answer.

Answer;

Lifting a 1 N box for 4 m, will take more work

Explanation;

Work is done when a an object with a certain weight is moved at a given distance;

It is the product of force and distance and therefore varies directly to both distance and force.

Work = Force × distance;

For a 4 N box 0.5 m;

Work = 4 × 0.5

        = 2 Joules

For a 1 N box 4 m

Work = 1 × 4

        = 4 Joules

Therefore, Lifting a 1 N box for 4 m, will take more work

It equals just about 6,300 km per hour each day an week
