Final answer:
The force pulling up a load with constant acceleration is greater than the weight of the load, as it must provide the upward acceleration in addition to counteracting gravity.
Step-by-step explanation:
When a load is being lifted with constant acceleration, the force pulling up the load must not only counteract the weight of the load but also provide the additional force required for the acceleration. Considering the weight w of the load is the product of its mass m and the acceleration due to gravity g, the total force Fs needed to lift the load with constant acceleration includes both the force to counteract gravity and the force to accelerate the load:
Fs = ma + mg
Here, ma represents the force needed to accelerate the mass, and mg represents the weight of the load. Therefore, the force pulling up the load is greater than just the weight of the load if the load is accelerating upwards.
