1)What is accomplished by this simple pulley'
It changes the direction of the force needed to lift the object
2) What advantage does a screw have over a nail
A screw can be inserted with less force than a nail.
3) 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?
The force decreases while the distance increases
4) What is the effect of using this inclined plane?
The object can be lifted with less force
The layout is the question is on the top and the correct answer is on the bottom
answers:
1) D: It changes the direction of the force needed to lift the object.
2) D: A screw can be inserted with less force than a nail.
3) D: The force decreases, while the distance increases.
4) C: To change the direction of the force applied to raise the bricks
5) D: The ramp reduces the mechanical force needed to move the refrigerator.
