Always take time to think because in real-life situations, most collisions are a combination of elastic and inelastic.

Examples of elastic collisions include:
- Two billiard balls colliding on a pool table without any loss of kinetic energy.
- Two air molecules colliding in a gas phase, bouncing off each other without any loss of kinetic energy.
- Two atoms colliding in a particle accelerator, where kinetic energy is conserved during the collision.
- Two cars colliding head-on with equal and opposite velocities, bouncing off each other without deformation or loss of kinetic energy.
- Two hockey pucks colliding on an ice rink and rebounding with the same velocity they had before the collision.

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.

- A ball with a mass of #9 kg# moving at #3 m/s# hits a still ball with a mass of #21 kg#. If the first ball stops moving, how fast is the second ball moving? How much kinetic energy was lost as heat in the collision?
- In a collision, do the two colliding objects have different acceleration values?
- Which has more momentum, a #8kg# object moving at #4m/s# or a #6kg# object moving at #6m/s#?
- How much momentum does a #15 kg# object moving at #6 m/s# have?
- A ball with a mass of # 5# #kg# is rolling at #4# #ms^-1# and elastically collides with a resting ball with a mass of #3# #kg#. What are the post-collision velocities of the balls?
