- 1. Multiple ChoiceWhat is a disadvantage of using an inclined plane to lift a heavy object?The object must be moved a greater distance.It takes less effort to move the object.Many objects are difficult to lift straight up.Heavy object usually take up more space.
- 2. Multiple Choice
Students pulled the same mass up an inclined plane that was 20 cm, 30 cm, and 40 cm long. Each time, they used a spring scale to measure the force needed to pull the mass up the inclined plane. What did they conclude?Less force was needed on the 20 cm planeMore force was needed on the 40 cm inclined plane.The least amount of force was needed on the 40 cm inclined plane.The least amount of force was needed on the 30 cm inclined plane. - 3. Multiple ChoiceAn inclined plane reduces the amount of force needed to move an object by -increasing the distance the object moves.transferring more of the force to the objectreversing the direction the object is moved.
- 4. Multiple ChoiceWhich of the following decreases when an object is moved using an inclined plane?The distance the object moves.The pull of gravity on the object.The force needed to move the object.The amount of space the object occupies.
- 5. Multiple Choice

- 9. Multiple ChoiceWhats an inclined plane?a sloping ramp up which heavy loads can be raiseda round machine used for travelinga ramp that launches planes
- 10. Multiple ChoiceHow does using an inclined plane make lifting a load easier?it makes the mass levitate upwardit increases the force needed to lift a massit decreases the force needed to lift a massit doesn't help
- 11. Multiple Choice
How does distance change the effort when using an inclined plane?
as distance increases, effort decreases
as distance decreases, effort decreases
as distance increases, effort increases
nothing, they both stay the same
- 12. Multiple Choice
Why is an inclined plane an example of a simple machine?
because it is a machine
because it makes work harder
because it makes the work easier
because it sounds cool
- 13. Multiple Choice
What happens as the incline increases?
effort increases
effort decreases
effort stays the same
- 14. Multiple Choice

an escalator
an uphill trail
a slide
a table
- 15. Multiple Choice
Movers needed to move a heavy box from the bottom of some stairs to the top of the stairs. They placed a ramp over the stairs and pushed the box up the ramp.
Which best explains why the movers used a ramp to move the box?
The ramp reduced the amount of
force needed to move the box.
The ramp increased the height that
the box needed to be moved.
The ramp reduced the distance that
the box needed to be moved.
The ramp increased the amount of
friction needed to move the box.
- 16. Multiple ChoiceThe greatest amount of force is required to move the metal block up which inclined plane?ABCD
- 17. Multiple Choice
Which of the following will require the least force to move the load up the inclined plane?
- 18. Multiple Choice
Which of the following statements best describes the situations?
Less force will be needed to move the box in Situation 2
Less force will be needed to move the box in Situation 1
More force will be needed to move the box in Situation 2
will take the same amount of force to move both boxes.
