When a volley ball and a tennis ball fall from the same height, which one will make your feet feel more painful when they are raised? Of course, the heavier one, right? That incident is one of the examples of the implementation of the momentum concept. Talking about momentum is certainly not separated from impulse.
0:33
So, what is momentum and impulse? Momentum is defined as the magnitude of difficulty in stopping an object. The magnitude of momentum is influenced by two things, namely weight and the speed of the object.
0:49
From the illustration, we can see that a car with high speed will also be faster. This can happen because the heavier a object, the greater its momentum. Likewise, with speed, the faster the object moves, the greater its momentum.
1:17
In physics, we know two kinds of momentum, namely linear momentum or P and angular momentum or L. From the right, a red car is very fast, while from the left comes a green car that is fast, because the speed of both cars is so fast that it ends up hitting. This is linear momentum, which is owned by objects that move straight or

or move in a translation. Well, while the angular momentum can be found when playing bianglala, where this bianglala moves in a circle and rotates on its porous.

One of the physical properties that mean its relationship with momentum is impulse. When playing football, we do the movement of kicking the ball, right? When kicking gives the ball a style by kicking, there is a period between the leg to touch the ball. Well, this is what is called an impulse. Simply, impulse is the change of momentum from one thing.
2:24
Looking at the illustration, it means that the impulse here depends on the style and time. A football player is kicking the ball with a size of 20 N. If the touch time between the leg and the ball is 0.01 second, how big is the impulse that occurs in the ball?
2:47
Okay, the pulse rate that works on the ball can be found by F times delta T. Then 20 Newton times 0.01 second.
2:59
0.2N is obtained in the direction of the average direction or F that is given to the ball. When discussing the momentum, we also do not get rid of the discussion of the mass that is defined as the interaction of two objects or more that change their style at a certain time and fulfill the law of momentum.
3:22
The law of momentum is sound. If there is no external force working on the system, then the momentum of a system will always be constant. A car has a mass of 1000 kg, and it goes at a speed of 110 km/h. Unintentionally, the driver of the car was hit by a 400 kg car. How much is the speed of the car and the car after the collision?
3:49
Well, this is a type of collision that is not at all easy because the time and speed of the car is greater than the decal. First of all, we write down the formula first. M1 multiplied by V1 plus M2 multiplied by V2 is the same as M1 multiplied by M2 multiplied by the speed of the speed after the collision.
4:10
M1 means the first mass of the object in kilograms, M2 the second mass of the object in kilograms, V1 the first speed of the object in meters per second, V2 the second speed of the object in meters per second, and V-accent is the speed of the object after the formation is not perfect. 1000 times 110 plus 400 times 0 equals to, in the curve, 1000 plus 400,
4:36
11,000 is equal to 1,400 multiplied by V accent. 11,000 divided by 1,400 is 7.85 km per hour. So we can find that the car's speed and also the traffic after the traffic jam is 7.85 km per hour.

Well, that was the discussion about momentum, impulse and growth. If you want to request a video, you can write it in the comments column. Hopefully useful, see you, bye bye.
