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 |
In perfectly elastic collision Kinetic energy is always conserved.
Correct option is B.
Option A is wrong, because there is no restriction of mass value in elastic collision, KE is conserved for all perfectly elastic collisions.
Option C is wrong, because kinetic energy is also conserved along with total momentum and total energy of system.
Let me know if you've any query.

In a perfectly elastic collision Momentum is always conserved Momentum is conserved only if all objects in the interaction have the same mass The final momentum cannot be determined None of these are correct
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?
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...
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...
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
Two objects collide and bounce off each other. Total kinetic energy is (A) definitely conserved, (B) converted to elastic energy, (C) definitely not conserved, (D) not necessarily conserved
V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...
True and False 1. If two particles of different masses have equal kinetic energy they also have equal momentum. 2. If the momentum of a single particle is zero, its kinetic energy may not be zero. 3. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 4. A large force always produces a larger impulse on a body than a smaller force. 5. If the kinetic energy of a single particle is zero, its momentum must...
and explain in detail please. Thankyou! 1. In a perfectly ELASTIC collision between two perfectly rigid objects A) the momentum of each object is conserved B) the kinetic energy of each object is conserved C) the momentum of the system is conserved but the kinetic energy of the system is not conserved D) both the momentum and the kinetic energy of the system are conserved
All collisions will be completely elastic - that is, the total kinetic energy of the system will be constant throughout. Also, the collisions are entirely one-dimensional, with all motion taking place in either the northward or southward direction. The setting: a room with a frictionless floor. A block of mass 1 kg is placed on the floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5 m/s. It eventually collides with a secondary, stationary block...
