(a) The linear momentum is conserved for all type of collision if net external force is zero in any collision.Only net external force to be zero is necessary condition for conservation of momentum
(b)The kinetic energy is conserved is elastic collsion while kinetic energy is reduced in inelastc collision while kinetic energy is increased in explosive collison

Contrast and compare elastic and inelastic collisions.
Question 4 options:
Both elastic and inelastic collisions have conservation of
momentum if there are no outside forces. They are different in that
elastic collisions bounce and inelastic collisions stick, and
kinetic energy is conserved in inelastic collisions.
They are basically the same thing, except the units are
different.

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...

Collisions are classified as elastic (kinetic energy is conserved), inelastic (kinetic energy is lost) or completely inelastic (the objects stick together after collision). Give an example of each type of collision. Is momentum conserved in each case?

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...

Our text has made a distinction between two different types of collisions according to whether kinetic energy is also conserved or not. Elastic collisions are said to conserve the total kinetic energy, while inelastic collisions result in some loss of energy. Provide and describe a real-life example of each type. Indicate where you think the lost energy went to for your inelastic example.

1) Why is there a different equation for elastic vs inelastic collisions? Are they really different? 5) If the first car does not go through either photogate after collision, what will its velocity essentially be? The conservation of momentum is a fundamental law in classical mechanics. It states that the total momentum of a system at the initial condition and ending conditions must be equivalent or p. - P. This can be modeled by studying the effect of objects in...

Two equal mass object experience a totally inelastic collision. Case 1: Mass 1 has an initial velocity of 10.0 m/s in the negative y-direction, while mass 2 has an initial velocity of 5.00 m/s in the positive x-direction. (2-D collision) Case 2: Mass 1 has an initial velocity of 10.0 m/s in the positive x-direction, while mass 2 has an initial velocity of 10.0 m/s in the negative x-direction. (1-D collision) What was kinetic energy conserved in each of the...
