How much lift do you need to have to overcome gravity?

To overcome gravity, an object must generate lift equal to or greater than its weight. This means that the lift force must be at least equal to the gravitational force acting on the object, which is calculated using the formula ( F = m \cdot g ), where ( F ) is the weight, ( m ) is the mass, and ( g ) is the acceleration due to gravity (approximately 9.81 m/s² on Earth). For example, if an object weighs 1000 N, it would need at least 1000 N of lift to ascend.
