inclined planes

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.

An 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 object
• reversing the direction the object is moved.
