Question

9. A college campus is adding a new wheelchair ramp to assist certain students who have physical disabilities. A wheelchair ramp is an example of a simple machine called an inclined plane. Which of the following statements best explains how the wheelchair ramp changes the force of someone using a wheelchair?

Answer 1

The wheelchair ramp reduces the amount of force needed by someone using a wheelchair to move up or down an incline, as the ramp allows them to travel a longer distance at a gradual slope rather than having to overcome the greater force required to go straight up or down stairs. This makes it easier and more efficient for the individual to navigate the campus.
