In this question, we have a table and we have a variety of objects with their mass is given to us and their velocities.
00:09
The mass is given in kilograms.
00:10
The velocity is given in metres per second.
00:13
And we're asked to calculate the momentum.
00:15
Now, momentum is equal to mass times velocity.
00:18
So momentum is equal to mass, mass multiplied by velocity.
00:29
And you can see that's reflected in the units.
00:31
Mass and kilograms, velocity meters per second, the units for momentum become kilogram metres per second.
00:38
So let's populate this table.
00:40
So we have a bird which weighs 0 .03 kilograms and is moving at 18 meters per second.
00:46
So 0 .03 times 18 gets you to 0 .54 kilogram metres per second...
