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?

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
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...
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...
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...
In perfectly elastic collisions Kinetic energy is conserved if all objects have the same mass Kinetic energy is always conserved Total energy is conserved but kinetic energy is not All of the above
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...
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.
Coefficient of Restitution = 0 Objectives: Partially elastic collisions are defined by the coefficient of restitution between the two objects. In this experiment you will a. Propose a procedure to measure the coefficient of restitution b. Determine the coefficient of restitution for a racquet ball c. Determine whether the coefficient of restitution depends on velocity Introduction An elastic collision is one in which mechanical energy is conserved. A perfectly inelastic collision is one in which some of the mechanical energy...
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...
We smashed carts into each other in elastic (or mostly elastic) collisions. But there are other pieces you can put on the carts that would make them stick together. Imagine we had done that, smashing a cart with mass m1=0.32kg and initial speed v0=0.95m/s into a second cart that is not moving. a)How much kinetic energy would be lost in the collision if the stationary cart's mass were m2=0.55kg?
