Momentum is just mass times velocity. We assume that given that you can do the arithmetic.

Does an object moving at a constant speed have momentum?
Yes. An object moving at all in any direction at any speed has momentum due to inertia.
As momentum of an object decreases what happens to the veocity?
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.
When the mass of a moving object is doubled and its speed remains the same its momentum?
If the mass is doubled,speed should be halved to conserve momentum.
Definition of Momentum in physics?
The momentum of a moving body is defined as the product of its mass and velocity. Notice that since 'velocity' has a direction as well as a magnitude (is a vector quantity), momentum also has direction as well as magnitude. That's why two billiard balls, moving toward each other each with the same exact speed, can completely stop dead after the collision ... since their velocities are in opposite directions, their momentums are also exactly opposite, and add up to zero.
Spaceship 1 and Spaceship 2 have equal masses of 200 kg. Spaceship 1 has a speed of 0 ms and Spaceship 2 has a speed of 10 ms. What is the magnitude of their combined momentum?
Momentum = mass x speedSince Spaceship-#1 is not moving, it has no momentum. Their combined momentumis that of Spaceship-#2 alone.Momentum = mass x speed = 200 x 10 = 2,000 kilogram-meters per second.
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.
Does an object moving at a constant speed have momentum?
Yes. An object moving at all in any direction at any speed has momentum due to inertia.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
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.
As momentum of an object decreases what happens to the veocity?
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector.

Why 3000 kg mass moving at .2 m s has a big momentum?
Momentum in classical mechanics is defined as mass times velocity. The magnitude of the momentum of an object with mass 3000kg and speed 0.2 m/s has a momentum of 600 mkg/s. A human walking at the same speed of 0.2 m/s weighing, let's say, 100 kg has a momentum of 20 mkg/s which is 30 times smaller.
Can you make a sentence with the word momentum?
yes A moving vehicle has momentum according to it's mass and speed.
Does a car traveling along a curved path at constant speed have a constant momentum?
No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.
