skateboard.....if velocity is zero,then momentum is also zero.
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
skateboard. momentum is mass times velocity thus if 0 velocity=0 momentum
The momentum of the heavy truck at rest is zero and so is definitely less than a moving automobile no matter how lighter it is than the heavy truck and how fast it is going - as long as it is moving.
Since momentum equals mass times velocity, if the mass of the truck times its velocity is greater than the mass of the bus times the bus' velocity then the momentum of the truck will be greater than the momentum of the bus.
If a car and a truck are traveling at the same speed, the truck would have more momentum because it has a greater mass.
A truck that is more heavy with the same velocity whil the truck is less heavy it will have more momentum!!
thunder, tensor, grindking, krux etc.
Momentum depends on both mass AND velocity. So if they are both going the same speed the truck would have more momentum. However, a car traveling at 44.7m/s (100mph) could have more momentum that a truck traveling at 0.1m/s p = m * v Momentum (p) is equal to the mass (m) of the object times its velocity (v). All in SI units.
