What has more inertia a truck or a skateboard?

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


How fast is moving a 10000lbs truck at 20mph strikes a 2000 lbs car at rest and all the momentum is transfered to the car how fast will the car be moving?

The car can't end up moving faster than the truck. Momentum doesn't affect speed, it only affects whether the truck can move the car. Since the truck weighs more, the car will be moved. If the truck is moving at 20 MPH, the car will start moving at 20 MPH on impact, but unless the truck continues moving and speeds up, the car won't move any faster than the original 20 MPH of the truck.


Why does a fast moving car have more momentum than a slow moving car?

A fast-moving car has more momentum than a slow-moving car because momentum is directly proportional to an object's velocity. The momentum of an object is the product of its mass and velocity, so the faster the object is moving, the greater its momentum.


A car and a truck are traveling at the same speedWhich has more momentum why?

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


Which of the following has greater momentum a 500 kg car moving at 64 km a 250 kg cart moving at 12 km or a 1000 kg truck moving at 32 km?

The momentum of an object is calculated by multiplying its mass by its velocity. Therefore, the momentum of the 500 kg car moving at 64 km/h is greater than the momentum of the 250 kg cart moving at 12 km/h or the 1000 kg truck moving at 32 km/h.


Does a truck have more momentum than a car?

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


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

A fast-moving car has more momentum than a slow-moving car of the same mass because momentum is the product of mass and velocity. Since the fast-moving car has a higher velocity, its momentum is greater. Momentum is a measure of the motion of an object, so the faster the object is moving, the more momentum it has.


Which law of motion is applicable to a moving car that makes it likely that it will be damaged when it collides with a truck?

The principle that might apply here is momentum. Momentum is mass times velocity. What should be pointed out is that velocity is speed that has a direction vector. (If the car is moving ahead in a straight line it is traveling at "x" miles per hour "forward".) The car is moving forward and comes into contact with the truck. That seems to be where the question is looking. The mass of the car times its velocity is its momentum, and this represents the energy that it is carrying into the collision. This energy will have end up being distributed among the various parts and components of the car and the truck that are compressed, deformed and/or broken by the collision. The amount of damage will be proportional to the momentum. The more the momentum (the more the "forward" energy) of the car, the more compression, deformation and breakage there will be.

Which has a greater momentum a heavy truck at rest or a moving automobile?

A moving automobile would have a greater momentum than a heavy truck at rest. Momentum is the product of mass and velocity, so even if the truck has more mass, the automobile's momentum would be greater due to its velocity.


When a toy truck collides into a toy car. the momentum of what is the same after and before the collition?

The total momentum of the system (toy truck + toy car) is the same before and after the collision, as long as no external forces are present. This is known as the principle of conservation of momentum.


What are some examples of momentum?

Momentum is speed or force of movement and it is defined as moving body. Momentum must have both mass and velocity. Examples of momentum include if a car and big truck are rolling down a hill, the truck will roll faster. A bullet has a lot of momentum with a small mass.


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.
