Here's why:
* Weight: Weight is the force of gravity acting on an object's mass. It's calculated by the formula: Weight (W) = mass (m) * acceleration due to gravity (g).
* Lifting: To lift an object, you need to exert an upward force that counteracts the downward force of gravity (its weight).
* Equilibrium: For the object to remain stationary or move upward, the upward force you apply must be equal to or greater than the downward force of gravity (its weight).
In simpler terms:
If an object weighs 10 Newtons (N), you need to apply a minimum of 10 N of force upwards to lift it.
Important Note: This assumes you're lifting the object straight up. If you're lifting it at an angle, the force required will be slightly higher due to the need to overcome both gravity and the angle of lift.
