Here's how it works:

* Decreased Force: Instead of lifting an object straight up, a ramp allows you to apply a force over a longer distance. This reduces the amount of force needed. Imagine pushing a heavy box up a ramp versus lifting it straight up - the ramp makes the task much easier.

* Increased Distance: To move an object the same vertical height, you need to travel a longer distance along the ramp. This is the trade-off for the decreased force requirement.

The ramp's angle determines the trade-off:

* Steeper ramp: Less distance, more force required.

* Shallower ramp: More distance, less force required.
