Momentum = (mass) x (velocity vector).

Given constant velocity, and assuming that mass doesn't change,

there is no change in momentum over time.

If there is any change in momentum, it can only be due to a change in mass.

It would change in direct proportion to the mass, and the direction of the

momentum vector would remain constant, in the direction of the velocity.

If the velocity is constant does that mean that the impulse is the momentum?

No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.


How do you find velocity when given mass and momentum?

To find velocity when given mass and momentum, you can use the formula: velocity momentum / mass. Simply divide the momentum by the mass to calculate the velocity.


How to calculate the change in momentum in a given scenario?

To calculate the change in momentum in a scenario, you can use the formula: Change in momentum final momentum - initial momentum. Momentum is calculated by multiplying an object's mass by its velocity. So, to find the change in momentum, subtract the initial momentum from the final momentum.


Why areal velocity is constant in central force?

In central force motion, the centripetal force acts perpendicularly to the velocity, causing the direction of the velocity to change but not its magnitude. As a result, the areal velocity (the rate at which the radius vector sweeps out area in a given amount of time) remains constant. This is a consequence of angular momentum conservation in a central force field.


What is the relationship between velocity and inertia?

Newtons First Law of Motion states that an object with a given momentum will continue to posses that same momentum until the object is acted on by a force in which case it will undergo a change in momentum. Inertia is a measure of an objects tendency to resist a change in momentum. Massive bodies have a large inertia. If a massive body is in motion its momentum is given by the product of the mass and the velocity of that body. Newtons first law says that if a force acts on this body its momentum will change. But since the body has a large inertia this change is small. For example, if a small space pebble collides with a large asteroid that has a constant velocity and thus constant momentum, the force is small relative to the inertia of the asteroid so the momentum only changes a little bit.

How do you find acceleration when given only mass and velocity?

You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.


How do you find mass if you are given the momentum and the speed?

momentum = mass x velocity => mass = momentum / velocity


If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?

It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v

How do you find the increase in kinetic energy if the percent increase in momentum is given?

Momentum = (mass) x (velocity), which is directly proportional to both mass and velocity.Since mass is constant, any change in momentum is the result of a change in velocity only.If the percent increase 'P' in momentum is given, velocity must have increased to (1 + 0.01P) of its original value.====================Kinetic energy = 1/2 (mass) x (velocity)2, which is directly proportional to mass and to the square of velocity.Since mass is constant, any change in kinetic energy is the result of a change in velocity only.If the velocity changes from its original value by a factor of (1 + 0.01P), the KE changes by a factor of (1 + 0.01P)2.The new KE is (1 + 0.01P)2 or [ 1 + 0.02P + 0.0001P2 ] times its original value.


What does it mean to say momentum is directly proportional to mass and velocity?

Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.


What happens to the momentum if the mass of the object increases?

If the mass of an object increases, its momentum also increases. Momentum is directly proportional to mass, so an increase in mass will result in a proportional increase in momentum, given that the velocity remains constant.


What is the calculation of momentum?

Momentum of a particle is the measure of quantity of motion in its and is given by product of its mass and velocity. That is p = mv ,if m and v are known ,momentum can be calculated.
