Orders of magnitude (momentum)
From HandWiki
The following table lists various orders of magnitude for momentum, in kilogram meters per second (kg·m/s).
Less Than 1 kg·m/s
| Factor (kg·m/s) | Value (kg·m/s) | Item |
|---|---|---|
| 10−24 | 2×10−24 | An electron in a hydrogen atom[1] |
| 10−3 | 0.00912 | A garden snail at its top speed[2] |
1 kg·m/s to 100 kg·m/s
| 100 | 1 | A 420 gram football (FIFA specified weight for outdoor size 5) kicked to a speed of 8.6 km/h. |
| 2.6 | 9x19 mm 7.5 gram pistol round launched at 350 m/s | |
| 3.8 | 5.56 mm (0.223) 4 gram rifle round launched at 945 m/s | |
| 5.83 | A fast baseball pitched in the major league.[3][4] | |
| 6 | The total impulse of a class C model rocket engine, which can be found in amateur fireworks. | |
| 6.52 | Planck momentum, the unit of momentum in the system of Planck units[note 1] | |
| 101 | 16 | The momentum of the famous football kick of the Brazilian player Roberto Carlos in the match against France in 1997. The football had a speed of 137 km/h, making it one of the hardest kicks measured. |
| 20 | The total impulse of a class D model rocket engine, which also can be found in amateur fireworks. | |
| 43 | 12.7x99 mm (0.50 BMG) 50 gram rifle round launched at 860 m/s | |
| 95 | An average person walking at an average walking speed |
Greater than 100 kg·m/s
| 103 | 2167 | A cheetah at its top speed[5] |
| 104 | 25050 | A regular small car weighing 1.5 tons crashing at 60 km/h |
| 27000 | A small car on a city street[6] | |
| 43420 | An SUV weighing 2.6 t (2.6 Mg) crashing at 60 km/h | |
| 108 | 1.1×108 | A cruising Boeing 747, with passengers and baggage.[7][8] |
| 4.95×108 | Apollo 11 launched from earth to orbit | |
| 1010 | 1.63×1010 | Space Shuttle launched from earth to orbit |
| 1025 | 7.52×1025 | Momentum of the Moon[9][10] |
| 1029 | 1.78×1029 | Momentum of the Earth[11][12] |
| 1032 | 1.215×1032 | Momentum of the Sun[13][14] |
