  2. Collision response - Wikipedia

    en.wikipedia.org/wiki/Collision_response

    The origin of the rebound phenomenon, or reaction, may be traced to the behaviour of real bodies that, unlike their perfectly rigid idealised counterparts, do undergo minor compression on collision, followed by expansion, prior to separation. The compression phase converts the kinetic energy of the bodies into potential energy and to an extent ...

  3. Static cling - Wikipedia

    en.wikipedia.org/wiki/Static_cling

    An electrostatic charge builds up on clothes due to the triboelectric effect when pieces of fabric rub against each other, as happens particularly in a clothes dryer. The separate positive and negatively charged surfaces attract each other. It is especially noticeable when humidity is low, allowing static electricity to build up.

  4. Coefficient of restitution - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_restitution

    The COR is a property of a pair of objects in a collision, not a single object. If a given object collides with two different objects, each collision has its own COR. When a single object is described as having a given coefficient of restitution, as if it were an intrinsic property without reference to a second object, some assumptions have been made – for example that the collision is with ...

  5. Inelastic collision - Wikipedia

    en.wikipedia.org/wiki/Inelastic_collision

    In such a collision, kinetic energy is lost by bonding the two bodies together. This bonding energy usually results in a maximum kinetic energy loss of the system. It is necessary to consider conservation of momentum: (Note: In the sliding block example above, momentum of the two body system is only conserved if the surface has zero friction.

  6. Elastic collision - Wikipedia

    en.wikipedia.org/wiki/Elastic_collision

    On average, two atoms rebound from each other with the same kinetic energy as before a collision. Five atoms are colored red so their paths of motion are easier to see. In physics, an elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

  7. Triboluminescence - Wikipedia

    en.wikipedia.org/wiki/Triboluminescence

    Triboluminescence is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed (see tribology). The phenomenon is not fully understood but appears in most cases to be caused by the separation and reunification of static electric charges , see also triboelectric effect .

  8. What is COVID rebound? Doctors explain common symptoms ... - AOL

    But it is difficult to know the exact number of people who get COVID rebound symptoms or test positive again after a negative test because many people who have rebound do not inform their doctors.

  9. Collision - Wikipedia

    en.wikipedia.org/wiki/Collision

    Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity). The magnitude of the velocity difference just before impact is called the closing speed.
