Well, the bearings doesn't care much if it's a 120 lbs rider or a 180 lbs rider - their drag is very much the same. The tires can easily be inflated a bit more for the heavier rider, making rolling resistance pretty much the same too. What's left is air drag, and the clue here is that a rider that's 50% heavier won't have a 50% bigger frontal area. So the lighter rider will only have a tad less wind resistance but a much lesser weight dragging him downhill.
The less air there is in the tires, the softer they become. The softer they become, the more they squish and deform at the contact patch with the ground, the more they deform, the more energy is soaked up by the tire. And that energy comes out of the speed of the bicycle.
Because when you're riding downhill gravity is helping by pulling you down, but when you're riding uphill you have to overcome gravity - just as when you're walking up a set of stairs.
higher inertial mass
In a river's lower reaches, where the slope is level and the banks wider apart, the flow is able to slow down as the water is able to spread out.
Gravity helps you move down the slope but works against you on the way up.

He slithered helplessly down the slope.
the answer s the slope how can it be slope it if it goes up and down slope is the measuer of x axis and y axis
a landform is a piece of land in the shape of something cool and a slope is something going down like when your going down a mountain your going down a slope
An undefined slope is just a line straight down. The slope is undefined.
No. Simply changing the gear without doing anything else won't slow a bicycle down. You can coast along without peddling and that will slow you down or you can use the brakes to slow the bike. Changing gears will affect the speed only if the current speed is slower than the highest speed you can reasonably attain with the selected gear - changing to a higher gear will help you speed up.
Yes, sometimes and no sometimes. In the case of rotating objects the more import value is moment of inertia. An object with a higher moment of inertia will accelerate slower (roll slower comparatively for any given time after release) down an inclined plane. In the case where the marbles are of equal diameter and uniform (although different if one is to have more mass) density the heavier marble will roll slower down a slope.
At the bottom of the slope?
