  ## What does Collision mean?
  
  1: an act or instance of colliding: clash. 2: an encounter between particles (such as atoms or molecules) resulting in exchange or transformation of energy.
  
  ## What are the 2 types of collision?
  
  There are two general types of collisions in physics: elastic and inelastic. An inelastic collisions occurs when two objects collide and do not bounce away from each other.
  
  ## What happens in a collision?
  
  A 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 ).
  
  ## What is collision in physics class 11?
  
  Collision means two objects coming into contact with each other for a very short period. In other words, collision is a reciprocative interaction between two masses for a very short interval wherein the momentum and energy of the colliding masses changes.
  
  ## What are the types of collision?
  
  Collisions are of three types:
  
  • perfectly elastic collision.
  • inelastic collision.
  • perfectly inelastic collision.

  ## What is the difference between an accident and a collision?
  
  A car “ accident ” could be many things, like a teenager running over a curb, or even someone spilling coffee inside a car. Technically, these are “ accidents.” But a crash, wreck, or collision implies that one vehicle came into contact with another and that one person is liable for the damages.
  
  ## What happens when two billiard balls collide?
  
  When two billiard balls collide the collision is nearly elastic. An elastic collision is one in which the kinetic energy of the system is conserved before and after impact. For collisions between balls, momentum is always conserved (just like in any other collision ).
  
  ## What is collision formula?
  
  An elastic collision is a collision where both kinetic energy, KE, and momentum, p, are conserved. This means that KE = KEf and po = pf. And, since p = linear momentum = mv, then we write m1v1i + m2v2i = m1v1f + m2v2f.
  
  ## What happens when two objects collide?
  
  Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
  
  ## Why is energy lost in a collision?
  
  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 together. This bonding energy usually results in a maximum kinetic energy loss of the system.
  
  ## How do you know what type of collision you have?
  
  When objects don’t stick together, we can figure out the type of collision by finding the initial kinetic energy and comparing it with the final kinetic energy. If the kinetic energy is the same, then the collision is elastic.

  ## Why it is important to study collision?
  
  Physicists use collisions to determine the properties of atomic and subatomic particles. This is fortunate since it provides a way around the analysis of the forces of interaction between two bodies as they collide, an otherwise formidable task.
  
  ## What is a one-dimensional collision?
  
  Two identical objects (such as billiard balls) have a one – dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
  
  ## What is a two dimensional collision?
  
  Total momentum in each direction is always the same before and after the collision. Total kinetic energy is the same before and after an elastic collision.
