This mini-lecture is based on "Physics in Motion" PBS series. Clicking on the first video will take you to the PBS site. The next two videos should start automatically. In this mini-lecture, there are three consecutive videos to watch.
After watching this video, you should be able to answer the following questions:
What is linear momentum?
How is the rate of change of momentum quantified?
Why does the rate of change of momentum matter?
What does the impulse-momentum theory say?
After watching this video, you should be able to answer the following questions:
What does the law of conservation of momentum say?
Which Newton's laws is directly linked to the conservation of momentum?
After watching this video, you should be able to answer the following questions:
What is the difference between elastic and inelastic collision?
What is the assumption about energy in a perfectly elastic collision?
To what forms of energy is the kinetic energy transferred during an inelastic collision?
Here is a fantastic show of the billiard balls' collisions, copied from LinkedIn.
