The bicycle would have the greatest impact force.
Thrice a year, with a 67.23948 % chance that they occur during July 14-28. This is because Newtons fourth law of bicycle riding accidents, which clearly show that during massive heat (July) the protein K276 is released creating a 79.8264 greater chance of a bicycle accident.
More massive objects have more relative inercia.
Hydrogen, helium, and carbon fuel are found in more massive stars. The diameter of more massive stars is bigger. Helium is found in greater abundance in more massive stars. The weight of more massive stars is greater.
You get them really cheap at international magic which is a massive magic shop in London.
Earth is more massive than Mars and therefore has greater gravity.
The more massive the objects, the greater the gravitational force between them. The gravitational force is affected by mass and distance. The closer two bodies are, the greater the gravitational force also.
We can't be entirely certain, but the Earth's axial tilt may be related to the massive collision with another (now extinct) planet; a collision in which the Moon coalesced from the debris. The same collision would certainly have affected the rate of spin of the pre-Earth.
If the MASS of the 1st Object in a COLLISION is too small to generate a FORCE large enough to overcome the INERTIA of the 2nd Object, then the more massive Object will not move. This could make it look like the more massive object is not REACTING to the Collision.
If gravity is moving the objects toward each other, a massive body (i.e. the earth) will be in the way. If the objects are at the same ditance from this body, a greater force is exerted on object A.
Titanic had a near-incident leaving Southampton when the massive draft of her hull almost created a collision with a nearby vessel.
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.
