  2. Elastic collision - Wikipedia

    en.wikipedia.org/wiki/Elastic_collision

    In physics, an elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net loss of kinetic energy into other forms such as heat, noise, or potential energy.

  3. Collision - Wikipedia

    en.wikipedia.org/wiki/Collision

    A "perfectly inelastic" collision (also called a "perfectly plastic" collision) is a limiting case of inelastic collision in which the two bodies coalesce after impact. An example of such a collision is a car crash, as cars crumple inward when crashing, rather than bouncing off of each other.

  4. Newton's cradle - Wikipedia

    en.wikipedia.org/wiki/Newton's_cradle

    This assumes perfectly elastic objects, so there is no need to account for heat and sound energy losses. Steel does not compress much, but its elasticity is very efficient, so it does not cause much waste heat. The simple effect from two same-mass efficiently elastic colliding objects constrained to a straight path is the basis of the effect ...

  5. 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 ...

  6. Inelastic collision - Wikipedia

    en.wikipedia.org/wiki/Inelastic_collision

    A completely inelastic collision between equal masses. A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies ...

  7. Collision response - Wikipedia

    en.wikipedia.org/wiki/Collision_response

    The degree of relative kinetic energy retained after a collision, termed the restitution, is dependent on the elasticity of the bodies‟ materials.The coefficient of restitution between two given materials is modeled as the ratio [] of the relative post-collision speed of a point of contact along the contact normal, with respect to the relative pre-collision speed of the same point along the ...

  8. Bouncing ball - Wikipedia

    en.wikipedia.org/wiki/Bouncing_ball

    [36] [37] Assuming perfectly elastic collisions, the basketball impacting the floor at 1 m/s would rebound at 1 m/s. The tennis ball going at 1 m/s would then have a relative impact velocity of 2 m/s, which means it would rebound at 2 m/s relative to the basketball, or 3 m/s relative to the floor, and triple its rebound velocity compared to ...

  9. List of formulae involving π - Wikipedia

    en.wikipedia.org/wiki/List_of_formulae_involving_π

    is the number of collisions made (in ideal conditions, perfectly elastic with no friction) by an object of mass m initially at rest between a fixed wall and another object of mass b 2N m, when struck by the other object. [1] (This gives the digits of π in base b up to N digits past the radix point.)
