moving truck

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)

dodge more power and last longer

40 m is the more reasonable length of a pick up truck

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.

It depends on the truck's velocity, but, for the same velocity, the 2000kg truck has more momentum than the 2kg truck.

moving truck

A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more 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

Momentum = Î¡ = mâ€¢v, m is mass in kg, and v is velocity in m/s. Both the semi and the linebacker are traveling at the same velocity. However, the mass of the semi is hundreds of times the mass of the linebacker. Therefore, the semi will have a much greater momentum than the linebacker.

Newton's laws of Motion state that Momentum is a product of Mass times velocity. Momentum = Mass x velocity. Therefore, a loaded truck needs a larger force to move it, and once it's moving, it needs more powerful brakes to stop it. So a fully loaded truck will have more momentum and be harder to stop than an empty truck.

The truck it has more weight behind it.

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.

A truck that is more heavy with the same velocity whil the truck is less heavy it will have more momentum!!

A truck that is more massive with the same velocity as the truck that is less massive will definitely have more momentum. This is illustrated in the equation for momentum:p = mvWhere p is momentum which is measured in Newton seconds, m is mass which is measured in kilograms, and v is velocity, measured in meters per second. If you plug in a larger mass for that same equivalent velocity, it will accordingly have more momentum.Also, if you just think about it, what would be harder to move: something with more mass or something with less mass?

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)
