Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.

If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
Weight requires the presence of gravity. Gravity is the force that pulls objects towards the center of the Earth, giving them weight. Weight is a measure of the force of gravity acting on an object.
If the weight is 300 pounds, you will need to apply a force of at least 300 pounds to lift it against the force of gravity. This force is known as the weight of the object.
The force required to pull a door depends on factors such as the weight of the door, the friction in the hinges, and any additional resistance from air pressure or seals. Generally, pulling a door requires enough force to overcome these resistive forces and accelerate the door in the desired direction.
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.
The work done to lift the weight is given by the formula: work = force * distance. Setting the work as the weight times the height raised, we can calculate the force required as follows: force = work / distance = (2000 N * 1 m) / 4 m = 500 N. This means a force of 500 N was required to raise the weight.
It certainly does. That's why you have to push it harder to accelerate it horizontally. But that "more weight" that it has is exactly the more force it needs for vertical acceleration, and that's why all objects fall with the same acceleration.
Speed and weight are related in that a heavier object requires more force to accelerate or decelerate, thus affecting its speed. In general, heavier objects tend to have lower speeds due to the increased force required to move them compared to lighter objects.
To calculate the force required to lift something with a pulley system, use the formula: Force = Weight / (number of supporting ropes). The weight is the force of gravity acting on the object being lifted. The number of supporting ropes is the number of ropes in the pulley system that are supporting the weight.
Force required to move a box of the same weight changes in the case of different surfaces in contact due to friction.
The force required to lift 100 pounds is approximately 100 pounds since the force needed to overcome gravity is equal to the weight of the object being lifted. This force, equivalent to the weight of the object, must be greater than or equal to the force of gravity acting on it.
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.
