When moving an object on an inclined plane, the output force required is generally **decreased** when you lengthen the ramp. This is because extending the length of the ramp reduces the angle of incline, leading to a smaller component of the gravitational force acting parallel to the surface of the incline.
However, the force required will never be equal to the weight of the object. Instead, the force needed to move the object up the ramp can be calculated as \( F = W \sin(\theta) \), where \( W \) is the weight of the object and \( \theta \) is the angle of inclination. The shallower the angle (or the longer the ramp), the less force is needed to move the object up the incline, though friction and other factors could also play a role in real scenarios.
To summarize:
- Lengthening the ramp generally decreases the force required to move the object up the incline.
- The force required is not equal to the weight of the object, as it depends on the ramp's angle and any friction present.
