No.

If a car and a truck are traveling at the same speed, the truck would have more momentum because it has a greater mass.

moving truck

Total momentum

It depends on how fast each is going and how much each weighs. Momentum is calculated by multiplying the mass of an object by its speed. A tiny bullet moving very fast can have more momentum than a huge truck if the truck is moving very slowly (or not at all). (bullet mass) X (bullet speed) > (truck mass) X (truck speed)

A body must have velocity in order to have momentum. The difference is that a 5000 kg truck has more mass and therefore more inertia (Newton's first law). Inertia is the resistance to change in motion and so that's where the misconception of momentum and mass occur.

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.

The truck has the most mass, but because it is at rest, the skateboard has the most momentum.

skateboard.....if velocity is zero,then momentum is also zero.

If a car and a truck are traveling at the same speed, the truck would have more momentum because it has a greater mass.

Yes. At the same velocity, a truck would have more momentum than a car as it has greater mass. Momentum is the product of mass and velocity: ρ=mv

skateboard. momentum is mass times velocity thus if 0 velocity=0 momentum

Momentum = mass * velocityTherefore the Volswagen rolling down the hill has greater momentum than the truck which is sationary.Volkswagen: momentum = mass * velocityTruck: momentum = mass * 0 = 0

Momentum is mass times velocity, if the velocity of the two are the same, the object with the greater mass will have proportionally greater 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.
