Newton's law of restitution

Explanation:

Newton's law of restitution states that when two bodies collide, the speed with which they move after the collision actually depends on the material from which they are made. The Coefficient of Restitution (e) tells us about the bounciness, or elasticity, of the collision.

the bal will not change its velocity.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
