I WONDER - What Is An Inclined Plane?

An inclined plane is a sloped surface that reduces the force needed to lift objects by allowing them to be pushed or pulled up the slope instead of being lifted vertically. This principle is used in ramps for loading goods or providing wheelchair access. The mechanical advantage of an inclined plane is determined by dividing the length of the incline by its vertical height.

What is an inclined plane?

• A flat surface set parallel to a horizontal surface

• A curved surface set at an angle to a horizontal surface

• A flat surface set at an angle to a horizontal surface

• A surface set at a right angle to a horizontal surface

How does an inclined plane help in lifting objects?

• It reduces the force needed to lift the object

• It changes the direction of the force applied

• It reduces the distance to lift the object

• It increases the weight of the object

What is a practical application of inclined planes?

• Using a pulley to lift objects

• Using a lever to move objects

• Using a ramp to load goods onto trucks

• Using a screw to hold objects together

What is the principle behind ramps used for wheelchair access?

• They provide a flat surface for movement

• They increase the height of the building

• They enable pushing or pulling up an inclined surface

• They allow vertical lifting of wheelchairs

How is the mechanical advantage of an inclined plane calculated?

• By dividing the vertical height by the length of the incline

• By multiplying the length of the incline by the vertical height

• By adding the length of the incline to the vertical height

• By dividing the length of the incline by the vertical height
