Why does a fast moving car have more momentum than a slow moving car of the same mass?

Momentum (p) is defined as mass (m) times velocity (v).
p = m*v
Therefore, if you increase velocity, you also increase momentum. You can easily observe this by noting that it takes more force to slow down a faster moving object than a slower moving object.

Would an oil ship moving at 10kmh have more or less momentum than a car moving at a speed of 100 kmh?
momentum is mass x velocity. Even though the car is moving ten times faster, the ship mass is hundreds of times more, so the ship has more momentum
If a compact car and an SUV were both moving at 50 mph which would have the greater momentum?
Since momentum is mass x velocity, the vehicle with the greater mass would have more momentum in this case.
Does a moving object have impluse?
More or less. Actually, a moving object has momentum - defined as mass times velocity. The word "impulse" is used for transfer of momentum, for example, in a collision. It has the same units as momentum, but the use of the word "impulse" seems inappropriate in this context.
If a green ball has a greater momentum that a orange ball and both balls are moving at the same velocity then?
The green ball has more mass than the orange ball. r=mv Momentum = mass x velocity.
If the momentum of an object changes and its mass remains constant?
Momentum = mass x velocity. Therefore, more mass will result in more momentum.
Does a tiny bullet have more momentum than a huge 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)
Which car has more momentum a car with the speed of 20 km per h or a car moving at 100 km per h?
Momentum = mass * velocity. If both cars have the same mass, then the faster one will have more momentum. Probably the slow car doesn't weigh 5 times as much as the fast one, so the fast one most likely has more momentum.

Which has greater momentum an old school freight train at rest or a roller skate moving downhill?
The Roller-skate Momentum = (mass) multiplied by (speed) . Anything moving has more momentum than anything that's not moving. The thing that's not moving has zero speed, so it also has zero momentum.
If a compact car and an SUV were both moving at 50 mph which would have the greater momentum?
Since momentum is mass x velocity, the vehicle with the greater mass would have more momentum in this case.
Why does a semi truck have more momentum than a bicycle?
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.
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
A air mass produces more severe weather?
fast moving
What has more momentum a car with a speed of 20 kmh or a car moving at 100 kmh?
The magnitude of momentum is directly proportional to speed. A car moving at 100 km per hr has 5 times as much momentum as a car with equal mass moving at 20 km per hr has.
