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 plane
• More 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.

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.

Which 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.
