Identify the conditions for an elastic collision in a closed system. check all that apply. energy is conserved. velocities may change. momentum is conserved. kinetic energy is conserved. objects stick together after the elastic collision. one object may be stationary before the elastic collision.

In an elastic collision:

There is no external net force acting. Thus, Momentum before and after collision is equal. Momentum remains conserved. Total energy always remains conserved as energy cannot be created nor destroyed. It can change from one form to another. There is no lost due to friction in elastic collision. So the kinetic energy is also conserved. Velocities may change after collision. If the masses are equal, the velocities interchange.

When one object is stationary:

Final velocity of object 1:

v₁ = (m₁ - m₂)u₁/(m₁ +m₂)

Final velocity of object 2:

v₂ = (2 m₁ u₁)/(m₁+m₂) =

Objects do not stick together in elastic collision. They stick together in inelastic collision.One object may be stationary before the elastic collision.

Thus, conditions for an elastic collision:

Energy is conserved. Velocities may change. Momentum is conserved. Kinetic energy is conserved.One object may be stationary before the elastic collision.

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
