Question

Which has more momentum? A paper airplane with a mass of 10g flying at a velocity of 4m/s or a real airplane that is parked at a runway with a mass of 1000kg and a velocity of 0m/s

Answer 1

The momentum is calculated by multiplying the mass and the velocity of the object.
momentum 1 : = (10 g)(4 m/s) = 40 g m/s
momentum 2: = (1000 kg)(0 m/s) = 0 kg m/s
Thus, the paper airplane has a greater momentum than the real airplane.
