Do you know that velocity has a big brother in Dynamics? It is called Momentum. You can find it when multiplying mass by velocity. Momentum is extremely important for redefining Newton's Laws of motion.
When two objects collide, they make a momentum exchange but the total momentum of the system remains unchanged. This conservation plays a vital role in considering collisions. Without this concept we couldn't make space rockets or understand the science behind snooker game.
So let's start from the scratch. First the introduction and then relationships and applications. When you finish this topic, you will master in answering all relevant questions.
Be serious, take notes and review your notes. This classroom is free of charge but your valuable time is the really valuable. Use it in the most efficient way.
Lesson 1
Let's learn what is momentum?
This video is an introduction to the concept of momentum and impulse. Momentum is nothing but the big brother of velocity. You will see a very easy approach for connecting kinematics and dynamics in this video using variety of examples. Impulse is nothing but change in momentum.
Lesson 2
Physics behind rockets
In this video you will learn:
1. The extended form of Newton's second law
2. How to solve Rocket problem based on momentum.
Rocket is a challenging problem in physics and after watching this video you will master in it.
Lesson 3
Secret of hovering!
In this video we will consider hovering of a helicopter or rocket from the perspective of momentum. We will have problem solving to fix it in our mind forever.
This is a challenging lesson in physics but you will learn it in a simple language. It is highly recommended to all physics educators and students.
Lesson 4
Action-reaction in different view
In this video you will see that conservation of momentum has a very close relationship with the Newton's 3rd law of motion. If the system is not acted by any external force, the total momentum of it remains constant. I will explain some real cases and we will solve a problem. This video is an important prerequisite for learning the collision.
Lesson 5
How much do you know about nozzle?
In this video we will consider how nozzle can create a reaction force by speeding up the water. This is a unique video. You will learn how to use conservation of momentum for a nozzle.
Lesson 6
Let's collide on straight line
In this video you will see:
1. What is collision in physics?
2. How many types of collision do we have?
4. How to use conservation of momentum and kinetic energy to solve collision problems?
This video is considering everything from the scratch and is useful for a wide range of learners in simple language.
Lesson 7
The big secret behind snooker game!
In this video we will consider collisions in two dimensional space like snooker balls. Rather than conservation of momentum and kinetic energy, we need decomposition of momenta in vertical and horizontal directions.
