This physics video tutorial explains the concept of impulse and linear momentum in one and two dimensions. It covers the law of conservation of momentum for collisions and conservation of kinetic energy for elastic collisions. This video contains plenty of examples, notes, formulas / equations, and practice problems for you to master the concept.

Here is a list of topics:

1. Momentum Definition - Mass in Motion - Mass times Velocity

2. Momentum: Vector Quantity - Magnitude and Direction

3. Units of Momentum - Kg m/s

4. Newton's Second Law of Motion - F=ma - Net Force is mass times acceleration

5. Net Force - rate of change of momentum

6. Impulse Momentum Theorem / Principle

7. Force, Impulse, and Change in Momentum Physics Problems - Calculating Final Speed / Velocity

8. Calculating Impulse Given Contact Time and a Constant Force Plus a Variable Force

9. Impulse - Area Under Curve of Force vs Time Graph - Calculus & Physics

10. Using Average Force to Calculate Impulse

11. Law of Conservation of Momentum - Isolated System - Internal Forces vs External Forces

12. Law of Conservation of Kinetic Energy

13. Inelastic Collision Momentum Problems - Two Objects Sticking Together

14. Bullet & Block of Wood Physics Problem

15. Football Momentum Problem - Halfback Tackled By Cornerback

16. Astronaut Throwing a Ball in Space Physics Problem

17. Man Throws Package From Boat Momentum Physics Problem

18. Recoil Velocity of Rifle Problem

19. Railroad Car Physics Problem

20. Rocket Expelling Gas Problem - Mass Flow rate & Velocity - Calculating Average Force Exerted By Rocket

21. Ballistic Pendulum Problem

22. Average Force Exerted By Wall on Tennis Ball - Given Contact Time, Mass, and Velocity

23. Initial & Final Momentum, Impulse, & Average Force Problem

24. Elastic collisions of Billiard Balls Physics Problem - Conservation of Kinetic Energy

25. Object exploding into two fragments problem

26. Collisions in Two Dimensions - Calculating Final Speed & Angle of The Second Ball

27. Physics & Calculus - Derivative of Momentum Function - Instantaneous Force

28. Integration or Antiderivative of Instantaneous Force Function is Impulse or Change in Momentum

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
