why inst velocity conserved in elastic an inelastic collisions?
I know momentum is conserved but why isnt velocity?
Do you suppose that your question hasn't been answered because physics tutors couldn't figure out what you are asking?
Do you mean?
Why isn't velocity conserved in elastic and inelastic collisions?
Please proofread before you post.
oh oops I am sorry i didn't even notice that
In the context of collisions, it is important to understand the difference between velocity and momentum. Velocity is a vector quantity that includes both magnitude and direction, while momentum is also a vector quantity but is solely dependent on an object's mass and velocity.
In an elastic collision, the total kinetic energy of the system is conserved. This means that the objects involved in the collision exchange energy without any loss to other forms, such as heat, sound, or deformation. Because the total kinetic energy is conserved, the objects must also retain their original velocities after the collision.
On the other hand, in an inelastic collision, the total kinetic energy of the system is not conserved. Some of the kinetic energy is transferred to other forms, such as heat, sound, or deformation, during the collision. Therefore, the objects involved in an inelastic collision generally do not retain their original velocities after the collision.
In both elastic and inelastic collisions, the conservation of momentum holds true. This means that the total momentum before the collision is equal to the total momentum after the collision. However, momentum alone does not determine the final velocities of the objects involved. Other factors, such as the coefficient of restitution or the nature of the collision, play a role in determining the final velocities of the objects in the system.
To quantify and calculate the velocities of objects involved in collisions, the conservation of momentum equation is used. By considering the initial and final momentum of the system, along with other pertinent information about the collision, such as the masses and velocities of the objects, one can solve for the final velocities using the principles of conservation of momentum.
In conclusion, while momentum is always conserved in collisions, velocity is not necessarily conserved. Whether velocity is conserved or not depends on the nature of the collision – elastic or inelastic – and the specific circumstances of the collision.
