... The bigger the mass of object and the faster it is moving, the more momentum it has. You will have to be able to use the equation: Momentum = mass x velocity (kgm/s) (kg) (m/s) Because it is velocity in the equation, momentum also has direction. So it is positive in one direction and negative in the ...
