What is the correct equation for the momentum of an object?Its mass multiplied by its accelerationIts velocity divided by its massIts mass multiplied by its velocityIts mass divided by its velocity2A light plane of mass 5,000 kg is travelling at 50 m/s.  Calculate its momentum.250,000 kg m/s50,000 kg m/s100 kg m/s0.01 kg m/s3A pond skater of mass 2 g is gliding over the surface of a pond at 0.1 m/s.  Calculate its momentum.20 kg m/s50 kg m/s0.2 kg m/s0.0002 kg m/s4A car of mass 2000 kg has a momentum of 50,000 kg m/s.  Calculate its velocity.25 m/s0.04 m/s20 m/s40 m/s5What does the Principle of Conservation of Momentum say?The total momentum of any particular object within a system before an event is equal to its total momentum after the eventIn an open system, the total momentum before an event is equal to the total momentum after the eventIn a closed system, the total momentum before an event is equal to the total momentum after the eventAll objects of equal mass will always have the same amount of momentum as one another
