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
1024 2×1024 An electron in a hydrogen atom[1]
103 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]
