If an object is stationary it has no velocity (or momentum), but if the object moves it now has velocity (or momentum). All objects have matter so have mass.
So all moving objects that have mass and velocity will have momentum.
Momentum is a vector quantity because it has size (magnitude) and direction.
The formula for momentum is: momentum = mass x velocity
Rearrange the formula for mass: mass = momentum ÷ velocity
Rearrange the formula for velocity: velocity = momentum ÷ mass
The unit for mass is: kg
The unit for velocity is: m/s
The unit for momentum is: kg m/s
