what is momentum of a fly if it's traveling 1 m/s and has mass of 0.0001 kg?

p = momentum
m = mass
v = velocity
in classical mechanics,,,
p = mv = .0001 kg x 1 m/s = .0001 kgm/s

Momentum refers to moving things. It is a product of the mass of an object and its velocity. Momentum is why the driver of a car applies the brake to stop the car rather than just taking his foot off the accelerator. The car has gathered momentum and will continue to move forward after the driver stops accelerating it.
The greater the mass of the object, the more the momentum. It is harder to stop a large tractor trailer than it is a small compact car. Freight trains take much longer to stop than a short passenger train.
The amount of momentum that an object has depends on two physical quantities: the mass and the velocity of the moving object in the frame of reference. In physics, the symbol for momentum is usually denoted by a small bold p ; so this can be written:
where:
p = mv
p is the momentum
m is the mass
v the velocity

Just to get your brain working. This is the Newtonian
definition and it is 'wrong' at speeds approaching
the speed of light
Einstein modified Newton's formula.
