If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
It is easier to lift an object underwater because the buoyant force exerted by the water helps support the weight of the object. On land, you have to lift the object against the force of gravity without any additional support.
You can move the fulcrum closer to the object you are trying to lift in order to make it easier to lift. This will increase the mechanical advantage of the lever, requiring less force to lift the object.
To lift a heavy object without a forklift, you can use techniques like using a lever and fulcrum, using a hoist or pulley system, or using a dolly or hand truck to help with moving the object. Make sure to use proper lifting techniques and get assistance if needed to prevent injuries.
When you lift an object, you are transferring potential energy to it. This potential energy is due to the object's position in the gravitational field. The higher you lift the object, the more potential energy it possesses.
The force required to lift an object is equal to the weight of the object, which is the mass of the object multiplied by the acceleration due to gravity (F = m * g). The force must overcome the gravitational force acting on the object in order to lift it.
Potential energy
It is easier to lift an object inside water because water exerts an upward buoyant force on the object which counteracts the force of gravity pulling the object downwards. This makes the object feel lighter and easier to lift compared to in air.

A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
