How much work does it take to lift a 180 N barbell?

What other information do you need to calculate the work done?

Mass is not necessary, what is the main thing we need?

Answer

The main thing we need to calculate the work done is displacement.

When calculating the work done to lift a 180 N barbell, the important information needed is displacement. The amount of work done can be calculated using the formula: Work done = Force × Displacement.

In this case, the force (F) exerted to lift the barbell is 180 N. The displacement (D) refers to the distance the barbell is lifted. By multiplying the force exerted by the displacement, we can determine the total work done in lifting the barbell.
