this is called law of conservation of momentum
The case you're describing is called an inelastic collision. Two objects collide, stick to each other and continue their motion as one body. Due to momentum conservation principle, sum of two bodies momenta before collision has to be equal to momentum of the one body after collision. pbefore = pfirst + psecond = m1v1 + m2v2 pafter = (m1 + m2)vcommon Since pbefore = pafter, (m1 + m2)vcommon = m1v1 + m2v2 We can get vcommon from that: vcommon = (m1v1 + m2v2) / (m1 + m2) [vi are velocities of bodies before collision and vcommon is a velocity after collision]
When water droplets collide and merge to form larger objects, it is called coalescence. This process is common in cloud formation and precipitation.
That is called an elastic collision, where momentum is transferred between objects but the total momentum remains constant. This means that the kinetic energy is conserved during the collision.
Yes, this is called "The Conservation of Momentum". It requires that the two object are "Elastic", that is they do NOT permanently DEFORM. Two automobiles colliding would be an "Inelastic" collision. Energy would be lost in the Deformation of the Sheet Metal of the car bodies, and the amount of Momentum would NOT be the same AFTER the crash.
When two objects collide, the impact depends on factors like their mass, speed, and direction of motion. The collision can result in a transfer of energy, momentum, and deformation of the objects involved. The impact can range from an elastic collision, where kinetic energy is conserved, to an inelastic collision, where some energy is lost due to deformation or heat.
momentum (vector)
The law you are referring to is called the Law of Conservation of Momentum. It states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Small objects flying through space that might collide with another object is called space debris. Space debris is basically a collection of spent objects that are left in space.

impulse
It means there is a quantity called "momentum", defined as velocity x time, that is conserved. That is, whatever interaction occurs, for example, objects bumping into other objects, the TOTAL momento will not change. In such bumping, momentum can be transferred from one object to another, of course. Note that since velocity is a vector, momentum is also a vector.
Yes, photons can interact with each other through a process called photon-photon scattering, where they can exchange energy and momentum.
The Law of Conservation of Momentum states that the total momentum of a closed system remains constant before and after a collision. This means that the momentum of an object before a collision is equal to the total momentum of the objects after the collision.
