What is the minimum force required to lift an object?
Click For Summary
SUMMARY
The minimum force required to lift an object must exceed its weight. In the case of a 60 kg individual, this translates to a force greater than 600 N, as calculated using the formula force = mass × gravity (where gravity is approximately 10 m/s²). The discussion highlights the distinction between total applied force and net force, emphasizing that while the scale reads 600 N when the person is at rest, any additional upward force (x N) must be applied to achieve upward acceleration. The conversation also addresses misconceptions regarding energy conservation, clarifying that the work done must account for both the gravitational force and the applied force.
PREREQUISITES- Understanding of Newton's Second Law (F=ma)
- Basic knowledge of gravitational force calculations
- Familiarity with concepts of work and energy in physics
- Ability to differentiate between net force and total applied force
- Study the implications of Newton's Second Law in dynamic scenarios
- Explore gravitational force calculations in different contexts
- Learn about work-energy principles and their applications
- Investigate the mechanics of human movement and muscle force generation
Physics students, educators, and anyone interested in understanding the mechanics of force, motion, and energy conservation in real-world scenarios.

Thanks a lot I appreciate it,malawi_glenn said:
But this is not the idea you should not die you will just feel some pain without belly damage. You will damage your belly if you put a +100 kg rock " equals to your weight" on your belly. Post #109
You lie on the belly " your picture" by +100 kg weight you do not hurt your stomach. You put the same weight as a rock of +100 kg on your belly, that will damage your belly severely. Big different scenarios even though both are of the same mass.

I can go and get a tractor tire of weight ~180 kg and roll it up my stomach. Then you will say it is not good because tractor tires are round or whatever
