Momentum = Mass x Velocity. (p=m*v)
The mass of an object made of matter can not be zero.
If the object (car) is moving, then the velocity will be non-zero, and the object will have non-zero momentum.
So, if you are driving or rolling the car, it has momentum.
If it is parked, then it will have 0 velocity (with respect to the earth), and thus will have 0 momentum.
So, when the car is moving, it has net momentum. When it is parked it has zero momentum. I then just becomes a mater of semantics whether having zero momentum is equivalent to not having momentum, or if it is actually a valid value for momentum or state of momentum.
What else can I help you with?
Does the mass of the car effect the speed?
A cars weight affects its speed by varying its momentum. If the car has more weight, it has more momentum. With more momentum comes more inertia.(definition: inertia- an objects resistance to change in direction or movement) If the car has a lot of weight, it will speed up slower and stop slower because the cars inertia and momentum keep propelling it forward. If a car has less weight, it will speed up faster and stop faster because the momentum of the car is less than that of the heavier car. A: It is called the power to weight ratio.
What is an example of low momentum?
Momentum = Mass x Velocity (p=mv)Of course an object at rest would have no momentum no matter what the mass is (velocity = 0 so momentum = 0).Playing volleyball with a balloon might be something that would be considered low momentum. You can hit it as hard as you like, but it has so little mass that its momentum can hardly overcome the air resistance.You might push a small car at, say 1/4 MPH, and it would have relatively little momentum.However a train traveling at the same 1/4 MPH would still have a lot of momentum.
Does the p in p mv mean position?
No it does not. It represents momentum.
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
When objects collide the totol inital momentum equals the total final momentum is what?
law of conservation of momentum
If you drop a suitcase out of a car what happens to the cars momentum?
If you drop a suitcase out of a moving car, the momentum of the car will decrease as there will be less mass, therefore less momentum. :)
Can a slower car have more momentum than a faster car?
Yes. The Formula for momentum is Momentum= Mass x Velocity. If the slower car has a larger mass, it will likely have a larger momentum.
A moving bumper car hits the back bumper of a stationary bumper car The momentum of the stationary car increases Which happens to the momentum of the moving bumper car?
The momentum of the moving bumper car decreases because some of its momentum is transferred to the stationary bumper car during the collision. According to the law of conservation of momentum, the total momentum of the system (both cars) remains the same before and after the collision.
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.
Explain how momentum is conserved when a car hits a bicycle?
When a car hits a bicycle, momentum is conserved because the total momentum of the system (car + bicycle) before the collision is equal to the total momentum after the collision. This means that the combined momentum of the car and bicycle remains constant despite the collision, with some of the momentum transferring between the two objects during the impact.
Why does a person without a seat belt continue moving in a car accident?
Momentum! Car has momentum before an accident, this momentum is transferred to the person after the car has made an abrupt stop (accident).
An example of momentum?
Momentum is motion. When a car is moving it is exhibiting momentum. A young professional getting promotions is experiencing momentum.
Which has greater momentum a car or a bike going at the same speed?
Momentum is calculated as the product of mass and velocity. Since a car typically has a much greater mass than a bike, even when both are moving at the same speed, the car will have greater momentum. Therefore, the car has greater momentum.
What has greater momentum a car standing still or a bug fyling?
Assuming that both the stationary car and the flying bug can be analyzed against the same reference point, the bug has the greater momentum. Momentum is defined as the product of mass and velocity. If the car exhibits no motion, then its momentum is zero. Since the bug is flying, it has nonzero velocity and a nonzero momentum, which is greater than the car's momentum.
When a toy truck collides into a toy car the momentum of the what is the same before and after the collision?
The total momentum of the system doesn't change. In this case, it refers to the momentum of the toy truck plus the momentum of the toy car.
What determines if one car has more momentum than another in a two-car collision?
The momentum of a car in a collision is determined by its mass and velocity. A car with greater mass or higher velocity will have more momentum than a car with less mass or lower velocity.
When moving freight car collides with an identical one that is at rest. If momentum is conserved what happens to the second car after the collision?
If momentum is conserved, the second car will start moving in the opposite direction with the same speed and momentum as the first car after the collision. This is due to the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
