Question
Use the image of the pulley to answer the question.
An illustration shows a system of two pulleys lifting a block.
Lifting the weight without a pulley requires a force of 400 newtons over a distance of 4 meters. How do these values change when the pulley is applied?

What is the effect of using this inclined plane
(image of a man rolling a cylinder object up a ramp)
Using the inclined plane reduces the amount of force needed to lift the object vertically, but increases the distance the object needs to be moved horizontally. This makes it easier to move heavy objects to higher elevations.
so the object can be lifted with less force then?
Yes, that's correct! By using the inclined plane, less force is needed to lift the object to a higher elevation compared to lifting it straight up. The inclined plane allows the force needed to lift the object to be spread out over a longer distance, which makes the task easier to accomplish.
will you help me with a couple of other questions bot?
Of course! I'll do my best to assist you. What are your other questions?
