What is the relationship between elastic collisions and kinetic energy?
Sebastian AcostaIn elastic collisions, kinetic energy is conserved.
In real life, truly elastic collisions happen only when no contact takes place. Billiard balls are nearly elastic, but careful measurement would show that some kinetic energy is lost. The only collisions that qualify as truly elastic would interact thru near misses of bodies in which there is either
I hope this helps, Steve

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- An astronaut with a mass of #75 kg# is floating in space. If the astronaut throws an object with a mass of #35 kg# at a speed of #5/6 m/s#, how much will his speed change by?
- Which has more momentum, a #500kg# object moving at #1/4m/s# or a #50kg# object moving at #20m/s#?
- A ball with a mass of #9 kg# moving at #3 m/s# hits a still ball with a mass of #12 kg#. If the first ball stops moving, how fast is the second ball moving?
- A ball with a mass of #4# #kg# and velocity of #5# #ms^-1# collides with a second ball with a mass of #6# #kg# and velocity of #-1# #ms^-1#. If #20%# of the kinetic energy is lost, what are the final velocities of the balls?
- A 2-kg blob of putty moving 3 m/s slams into a 2-kg blob of putty at rest. What is the speed of the two stuck-together blobs of putty immediately after colliding? What is the speed of the two blobs if the one at rest was 4-kg?
