Inclined Plane

What 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.

How can you decrease the effort force needed to push a mass to the top of the ramp?

• cover the surface with carpet

• increase the length of the ramp

• increase the height of the ramp

• decrease the length of the ramp

Which of the following does a simple machine do?

• allows the users to apply less force over a longer distance.

• reduce the amount of force needed to do work.

• change the direction of the applied force.

• All of the above.

Students want to raise a large crate from the ground to a deck several feet above the ground. They know it will be easier to move the crate along an inclined plane because the inclined plane will —

• A. reduce the work needed to raise the crate.

• B. increase the force applied to the crate.

• C. increase the work done on the crate.

• D. reduce the force necessary to raise the crate.
