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. |
|
Elastic collisions do not have conservation of momentum 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 not conserved in inelastic collisions. |

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?
Consider four types of collisions: inelastic, totally inelastic, elastic and explosive. (a) For which of these collision types is total linear momentum conserved? Do you need anything special for the momentum to stay constant? Explain! (b) For which of these types of collisions is kinetic energy the same before and after the collision? For each type, if the final kinetic energy is different than the initial, state whether kinetic energy has increased or decreased, and what other types of energy...
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...
Kinetic energy is only conserved in an inelastic collision. True False Two objects collide ans stick together. This is an elastic collision. True False Momentum is conserved in both elastic and inelastic collisions. True False
stion 5. Comment on momentum conservation for the inelastie collisions. » u can find patterns in momentum conservation according to whether one carton were moving before the collision, and whether the masses of the carts were ncany or very different. collisions. See if Fone cart or two were nearly equal Question 6. Explain what happens to the momentum in each of the cases. Loo the total momentum is divided un between the two carts after the collisions, compared to how...
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...
please help with question 4. EXPERIMENT4: THE LINEAR AIR TRACK The aims of this experiment are to: 1)investigate momentum and energy conservation in coll 2. study the cooversion of energy for a body in free fall. There are two types of collisions, elastic and inelastic. In both types of collision momentum is between two bodies in one dimension. The velocity (and hemee the momentum) may be positive or ycorserved. A body of mass m moving with a velocity vi has...

16. In a perfectly elastic collision Kinetic Energy is conserved for the system. (Remember that elastic collisions are ones where the objects bounce off of each other and don't stick.) On an air hockey table two identical pucks collide. Initially one is at rest and the other is moving with a speed of v. (Hint: How can the concept of momentum help with this problem?) a. What is the speed of each puck after the collision in terms of the...
