The property that makes the object difficult to lift is its weight.
The property that makes an object difficult to lift is its weight. Weight is the force exerted by gravity on an object and is directly proportional to an object's mass. To calculate the weight of an object, you can use the equation W = m * g, where W represents weight, m represents mass, and g represents the acceleration due to gravity. The weight of an object can make it difficult to lift, especially if the object is heavy.
