Inertia
Planetary accretion is the process by which smaller particles in a planetary system collide and stick together, gradually building up larger bodies like planets. This process is driven by gravity, as particles attract each other and form into increasingly larger objects over time. Accretion is a key step in the formation of planets from the protoplanetary disk around a star.
When particles come together. Therefore, collide. After that they react.
accretion
When particles collide, they transfer energy and momentum.
All particles of all things are in constant motion. Particles in a liquid collide, but the rate is subdued by the viscosity of the liquid.
Satellites have different aerials and orbits in order to ensure they do not collide or send mixed signals. Satellites are a vital part to the advancement of technology in the world.
No, it is not true. They do hit planets sometimes.
Since they collide at very high energies, it is expected that they will produce some new particles, that were not yet observed previously.
collide means to crush together forcefully and hardly
When particles collide, they transfer energy and momentum to each other through interactions such as scattering or absorption. This transfer can result in changes in the direction, speed, or properties of the particles involved in the collision.
When they collide with other particles or a surface (wall of a tank).
