the universe was once much smaller, supporting the big bang theory which
states that all the matter in the universe once occupied a single point
with infinite density.
The speed of an object in a set direction is its velocity.
We know that impulse is simply the product of Force and time:
Impulse = Force * time
Since Force has a unit of Newton or kg m/s^2 and time is in
seconds, therefore impulse can have units as:
N s
or
