Why do we have to use force to lift any object what do machines do to force we apply

Dear Student,

Solution:
We need force to lift objects to overcome the force of gravity(weight of the object).

Machines help humans increase and/or redirect the force applied to an object. The main benefit of machines is that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance.
