Here's why:
* Weight is the force of gravity acting on an object's mass. It's calculated using the formula: Weight (W) = Mass (m) * Acceleration due to gravity (g).
* To lift an object, you need to apply a force that counters its weight, essentially pushing against the downward force of gravity.
Therefore, to lift an object, you need to apply a force equal to its weight to overcome the gravitational pull.
