What degree of difference in gravity is noticeable?

Setting: Earth and an Earthlike planet with slightly lower gravity, linked by a portal (just step through and you're there

I did a google search of "astronauts walking on moon gravity" since that is the known human experience of walking in lower gravity. These two links, at a quick look, seemed to provide interesting information

If I understand correctly, losing 10-20% of gravity would be close to what you experience in the elevator when it goes down. The only difference is that the elevator usually only accelerates for a brief period of time, and then goes with the constant speed (which would be roughly the same as not moving at all).

For fictional depictions, see Barsoom, and Lewis's OUT OF THE SILENT PLANET.

I concur with this. If the "portal" generates enough sensory stimulation it's quite possible that you could arrive at the other end and either not notice the difference in your weight, or simply attribute it to how emotionally and physically worked up you were by the journey. So long as the new gravity was at least 75% of Earth or thereabouts, as at such gravity the biomechanics of walking and running don't change much

You'll be 25% stronger at the 80% (50% you're twice as strong, FYI), and a definite "spring in your step," according to my husband. You'd have to watch running (not walking necessarily) up steps because you're likely to overestimate push-off and tumble; taking two at a time would be a lot easier.
