Central and absolutely elastic collision of two balls of identical masses. After collision the incident ball is stopped. The ball, which was initially at rest, after collision will move with initial velocity of incoming ball. That is, the balls just exchange the velocities.

Central and absolutely elastic collision of two balls of different masses. The mass of incoming ball is greater than the mass of a still ball. After collision the balls move in one direction.

Central and absolutely elastic collision of two balls of different masses. The mass of incoming ball is smaller than the mass of a still ball. After collision the balls move in opposite directions.

Transfer of the pulse along a chain of absolutely elastic balls of identical masses. Only the last ball continues the motion.

Newton's cradle demonstrates conservation of momentum and energy during the central collisions of the balls.

Collision of an elastic ball with the wall is accompanied with excitation of the flexural oscillation of it.

Central and absolutely elastic collision of a ball with a still oscillator. At the moment of collision the spring does not influence the balls and the incoming ball is stoped.

Central and absolutely elastic collision of a ball with a still oscillator. Oscillator is set into the motion and then collides the other still ball.

Eccentric and absolutely elastic collision of two identical balls. After collision the balls will move under the right angle to each other.

Scattering the group of light particles onto the other group of heavy particles.

Damping of the heavy particle by the collisions with the light particles.
