0.300 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.200 kg puck moving initially along the x axis with a speed of 2.00 m/s. After the collision, the 0.200 kg puck has a speed of 1.00 m/s at an angle of 53.0 degrees to the positive x axis. a) (6pts) Determine the velocity (speed and direction) of the 0.300 kg puck after the collision. b) (4pts) Find the fraction of kinetic energy transferred away or transformed to other forms of energy in the collision.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

"induction" is the process of charging an object without touching it.hope my answer has you : )
