Answer a structured blank, then explain the reasoning in writing.

A crate of mass m=5kgm=5\,\mathrm{kg} is raised to a platform of height h=2mh=2\,\mathrm{m}. It can be lifted straight up or pushed up a frictionless ramp of length L=5mL=5\,\mathrm{m}. Use g=10m/s2g=10\,\mathrm{m/s^2}.
The work done against gravity is
J\mathrm{J} for either path.
Explain in 1-3 sentences why the ramp can feel easier even though the work against gravity is the same.
