Elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Inelastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Perfectly elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Questions1. Was momentum conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining momentum.2. Was total velocity conserved for all types of collisions you examined...
Background Info: In this experiment you will observe and analyze elastic and inelastic collisions in one dimension and in two dimensions. You will measure the final momentum of a system after it explodes. You will see how both kinds of collision affect the kinetic energy of a system that consists of two frictionless carts. You will determine the momentum of two carts after they collide when one cart is initially stationary. You will analyze the results qualitatively as well as...

Explain which statements are wrong in the KMT and how it needs to be corrected. The Kinetic Molecular Theory Postulates The experimental observations about the behavior of gases discussed so far can be explained with a simple theoretical model known as the kinetic molecular theory. This theory is based on the following postulates or assumptions. Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion. These particles move...
