Size does not but mass does.
An object's size does not directly affect its gravity. Gravity depends on an object's mass and distance from other objects. However, larger objects with more mass tend to have stronger gravitational pulls.
Midi size rugby balls are size 2 and Super-Midi size rugby balls are size 3.
Size 5 for top level rugby.
Gravity is determined by mass. The greater the mass of an object, the stronger its gravitational pull. Size does not directly affect gravity, but a larger object may have more mass, leading to a stronger gravitational force.
The force of gravity acting on an object is directly proportional to its mass. This means that the larger the object, the greater the force of gravity acting upon it.
Rugby player Ben Cohen is in the media from time to time. However his shoe size has never been addressed publicly.
Not at all there are a huge number of soccer players and rugby players with size 13 feet.
All rugby games are required to use the IRB standard ball size for any matches. Only exclusions to this is junior rugby
Only if it's falling through air. If it's just the falling object and gravity, then no.
It does not. Mass is independent of where an object is. Weight, however, will vary in direct proportion to the planet's gravity.
Gravity would affect a hummingbird and an eagle differently due to their size and weight. The hummingbird, being much smaller and lighter, would be more significantly impacted by gravity compared to the larger and heavier eagle. The hummingbird would need to expend more energy to counteract the force of gravity while hovering and flying, whereas the eagle would have an easier time gliding and soaring due to its size and wingspan.
