Which has more momentum, a car traveling at 12 km/h or a bicycle traveling at the same speed ? Explain why

Sagot :

The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

Hi there!

The car.

Recall the equation for momentum:

[tex]\large\boxed{p = mv}[/tex]

m = mass (kg)

v = velocity (m/s)

Thus, if both objects have the SAME velocity, the object with the greater MOMENTUM would have a larger MASS.

A car's mass is greater than that of a bicycle, so the car would have a greater momentum.
