Incline Planes

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.

• 1

• 2

• both

• none

How does an inclined plane make work easier?

• By increasing the distance over which a force is applied

• By decreasing the distance over which a force is applied

• By increasing the force required

• By decreasing the force required

What is the effect of increasing the length of an inclined plane while keeping the height constant?

• It decreases the mechanical advantage

• It increases the mechanical advantage

• It has no effect on the mechanical advantage

• It decreases the force required to move an object

Which of the following is NOT a benefit of using an inclined plane?

• It reduces the force needed to lift an object

• It increases the distance over which the force is applied

• It changes the direction of the applied force

• It allows for the movement of heavy objects with less effort

What is the main advantage of using an inclined plane?

• It reduces the amount of work needed

• It increases the amount of work needed

• It changes the direction of the force

• It allows for the application of a smaller force over a longer distance

Which of the following is a benefit of using an inclined plane in construction?

• It requires more energy to move objects

• It allows for the lifting of heavier loads with less force

• It decreases the distance over which objects are moved
