[00:00:43]Yes. Come on. Come on. Come on. Good.

[00:00:46]Good. Good. Good. Very good. Super.

[00:00:49]Early morning.

[00:01:04]yellow heart in the very literally I got really goosebumps.

[00:01:38]I'm so happy.

[00:01:58]Right. Super. Good. Good. Good. Good.

[00:02:01]Very good. Very good. Very good.

[00:02:04]So, it's great.

[00:02:07]So, I just want to record it.

[00:02:26]You are going to put yellow heart right don't go So 5:45 Literally, it's so happy. So happy.

[00:03:14]You guys rocked it.

[00:03:20]Huh?

[00:03:35]Okay.

[00:03:47]Night study. Night study. Night emoj Right.

[00:04:20]Consistency.

[00:04:45]You have to just like this smash button and share it to your classmates.

[00:05:13]11.

[00:05:21]So okay. So this year, this year, this year, first night study is going to be on this Saturday.

[00:05:50]Saturday night study problems.

[00:06:05]problem. First problem, right?

[00:06:19]Right. Saturday night. Okay. Monday morning. Monday early morning. So, Saturday, Sunday, Monday early morning 3 class. Okay.

[00:06:35]Saturday night study. Monday to Saturday early morning classes. Saturday night study.

[00:07:01]Doubt doubt description.

[00:07:36]first time in the whole YouTube long ancestor along with The image we are going to study long answers we are going to study along with the images.

[00:07:59]Ready button.

[00:08:18]Yes. So we are going to see this. for assertion reasons.

[00:08:38]Thank you for that.

[00:08:40]Good. First question, what are what is inertia and its types?

[00:08:46]Explain the types of inertia.

[00:08:59]Rest. Inertia of rest.

[00:09:02]Motion direction.

[00:09:14]Motion side. Right.

[00:09:25]Rest.

[00:09:47]First, inertia of rest. Inertia of rest until unless external forces applied.

[00:10:15]Resistance of a body to change its state of rest is called inertia of rest.

[00:10:36]for the resistance of a body to change its state of rest.

[00:11:01]Inertia of rest is called inertia of rest.

[00:11:15]pen resting on a table.

[00:11:21]When you vigorously shake the branches of tree, some of the leaves and fruits get detached and fall down.

[00:11:42]of rest.

[00:11:44]Inertia of motion. Motion. Inertia of motion.

[00:12:08]Last year, inertia of motion. Inertia of motion.

[00:12:23]The resistance of a body to change its state of motion. Now, Sir, captain very bad.

[00:12:52]This is called in motion resistance.

[00:13:08]force stop. So until unless external force is applied force motionist resistance of a body to change its state of motion.

[00:13:28]Long jump. Long jump.

[00:13:57]That means run some distance before jumping because this will help him jump longer and higher.

[00:14:14]Right. Cricket balling resistance.

[00:14:36]Sorry boys. Sorry girls. Resistance of a body to change its state of rest.

[00:14:45]is called rest.

[00:14:50]Resistance of a body to change its state of motion is called motion.

[00:14:56]Long answer in the resistance of a body to change its state of is called inertia of same motion. Okay.

[00:15:34]Direction change its direction of motion. Change its direction of motion.

[00:15:40]Is inertia of motion.

[00:16:02]spelling turning a car.

[00:16:08]The resistance of a body to change its direction of motion is called inertia of direction.

[00:16:21]When a moving car takes a sharp turn, passenger tend to lean sideways due to inertia of direction.

[00:16:30]Public example. Turning of a car.

[00:16:39]Turning of car school.

[00:16:56]for right to lean sideways due to inertia of direction. That's it.

[00:17:20]In rest, of rest of motion, motion direction. direction.

[00:18:28]300 reach. 300 reach 300.

[00:18:36]If we reach 300 Newton's law of motion, Newton's law of motion. Explain Newton's law of motion.

[00:19:01]What is that? Rare in the sense.

[00:19:12]We are going to use it.

[00:19:23]Main content lesson.

[00:19:31]target Newton's first law of motion law of First unbalanced external force.

[00:20:07]So don't compare with that compare.

[00:20:14]But you can use this.

[00:20:30]Okay.

[00:20:40]Newton's first law of motion law of inertia. Law of inertia.

[00:20:47]Every body continues to be in its state of rest or state of uniform motion along a straight line unless acted upon by some external unbalanced force.

[00:21:02]for frictiction.

[00:21:29]Okay.

[00:21:36]Okay. Right. Right. Right. 300. Yeah. We got 300. Super. Super. Good. Good. Good.

[00:21:44]Very good. Today also we have achieved it. Right.

[00:21:50]Super level. Level.

[00:22:03]Yes, we have reached 300.

[00:22:10]Good. Good. Super. Good. Good.

[00:22:16]Means friction. Friction.

[00:22:22]Right.

[00:22:24]Super.

[00:22:43]Frictional force circle.

[00:23:19]It will be always in motion.

[00:23:31]Unless an external unbalanced forces external force.

[00:24:01]Everybody continues to be in a state of rest of uniform motion along a straight line unless acted upon by external unbalanced force.

[00:24:30]simple radar. Everybody continues to be Everybody continues to be in a state of rest or a uniform motion along a straight line. Motion straight line unless acted upon by an external unbalanced force.

[00:24:58]for your body will be in state of rest or state of uniform motion.

[00:25:21]The body resist the resistance of a body to change its state of rest.

[00:25:36]Resistance resist right. Okay.

[00:25:50]Newton's second law.

[00:25:54]Law of force.

[00:25:56]Law of force.

[00:25:58]Law of force.

[00:26:01]Law of force. Law of motion. Law of force. The force acting on a body is directly proportional to the rate of change of linear momentum of a body. And the change in momentum takes place in the direction of force.

[00:26:42]objective.

[00:27:06]enthusiasm, happiness, force is directly proportional to Change in momentum.

[00:27:28]Delta change.

[00:27:36]Okay. BMW.

[00:27:38]BMW.

[00:27:41]BMW.

[00:27:51]BMW.

[00:27:58]original BMW.

[00:28:11]Next, force is directly proportional to change in momentum.

[00:28:21]symbol.

[00:28:26]Delta P.

[00:28:50]Force acting on a body force is directly proportional. Directly proportional directly proportional rate of change of linear momentum.

[00:29:07]Change delta linear momentum P force is directly proportional to delta V.

[00:29:14]Force is directly proportional to delta PLA.

[00:29:37]Fala force equal to mass and acceleration.

[00:29:47]Second answer, right? Force is directly proportional to delta P.

[00:30:03]Force acting on a body directly proportional to rate of change of linear momentum of the body and the change in momentum takes place in the direction of the force. Change in momentum direction of the force. Force okay law of motion.

[00:30:27]Second law of motion.

[00:30:33]Okay. Newton's third law. One of the easiest and friendly for every action there is a equal and opposite reaction. They always act on a two different bodies.

[00:30:52]Equal and opposite reaction.

[00:31:06]Very easy. Okay. Very very easy.

[00:31:21]The second law of motion deduce the equation. One of the super duper derivation.

[00:31:30]Deration F= M by T by Tal Rocket.

[00:31:57]Okay.

[00:31:59]Thanks.

[00:32:05]We have to cross 500 in the early morning attendance.

[00:32:26]How rocket will go?

[00:32:48]Right. Right.

[00:32:52]Right. Described rocket propulsion.

[00:32:55]Rocket that we will see. Simple.

[00:33:09]So first point propulsion of rocket is based on law of conservation of linear momentum as well as Newton third law of motion.

[00:33:33]linear momentum change in linear momentum.

[00:33:44]Okay.

[00:34:01]conversion.

[00:34:15]First point, sorry 10 minutes.

[00:34:23]conservation of linear momentum as well as Newton's third law of motion rocket propulsion rocket first rockets are filled with fuel in the propellent tank for example rocket liquid propellent.

[00:35:04]When the rocket is fired, this fuel is burnt and a hot gas is ejected with a high speed from the nozzle of the rocket producing a huge momentum.

[00:35:23]Nozzle.

[00:35:31]Rocket.

[00:35:36]We see that rocket is like we usually think that rocket is like this.

[00:35:46]So how this rocket rocket gas.

[00:36:21]Rocket Super good, right?

[00:36:54]Right.

[00:36:57]So to balance this momentum an equal and opposite reaction is force.

[00:37:21]Rocket diagram to balance this momentum an equal and opposite force is produced in the combustion chamber which makes the rocket project forward.

[00:37:42]Rocket when in motion.

[00:38:03]When in motion, the mass of the rocket gradually decreases until the fuel is completely burnt out. Fuel since there is no net external force acting on it. The linear momentum of the system is consumed.

[00:38:45]Already pick up free fall effect. Super.

[00:39:04]The mass of the rocket decreases with altitude. Altitude which results in the gradual increase in velocity of the rocket.

[00:39:17]Rocket speed.

[00:39:30]Escape velocity.

[00:39:49]for escape velocity escape velocity simple linear momentum's third linear momentum The linear momentum is conserved.

[00:40:48]Newton's third law of motion simple YouTube I'm going to start a series operation operation start. So get ready for that.

[00:41:34]for YouTube.

[00:41:44]Very good. Super daily PDF OD square OD square OD square. Get ready for that.

[00:42:03]H.

[00:42:08]Okay. What is altitude altitude?

[00:42:30]One day, one detail.

[00:42:37]Oh my god.

[00:42:40]One detail one detail. Okay. Right.

[00:42:44]Operation century. Operation 75 out of 75. Operation 50 out of 50. We will start the operation 50 out of 50.

[00:42:56]So 50 out of 50 operation. So that I'm going to launch it master right ta bye-bye see you thank you if you can't then who can byebye 500 Bye.
