An inelastic collision is a type of collision in which kinetic energy is not conserved. This means that the total kinetic energy of the system before the collision is not equal to the total kinetic energy after the collision. In an inelastic collision, some of the kinetic energy is converted into other forms of energy, such as heat or sound.
Inelastic collisions can cause a change in angular motion by transferring momentum between objects. This can result in a change in rotational speed or direction of an object, depending on the angle and point of impact.
An elastic collision is one in which kinetic energy is conserved, meaning the total kinetic energy of the system before and after the collision is the same. In contrast, an inelastic collision does not conserve kinetic energy and some energy is lost during the collision.
In an inelastic collision, momentum is still conserved even though kinetic energy is not. This means that the total momentum of the system before the collision is equal to the total momentum after the collision. This can result in changes in the individual momentums of the objects involved.
One example of an inelastic collision that impacts angular motion is a car crash. When two cars collide, some of the kinetic energy is converted into other forms of energy, such as heat and sound, and the cars may experience changes in rotational speed and direction. Another example is a basketball bouncing on the ground, where some of the kinetic energy is lost as the ball deforms and changes direction, resulting in changes in its angular motion.
