What is the momentum of a 30g body moving to the right at a velocity of 2m per sec?

Momentum equals mass times velocity. Mass is traditionally in kilograms, so let's convert those 30 grams into kilograms:
30 g * (1kg / 1000g) = .03 kg
p = mv
so,
p = (.03 kg)(2 m/s)
= .06 kg m/s

Which determines the momentum a moving body?
The product of mass and velocity determines the momentum of a moving body.
Does a body moving with uniform acceleration have momentum?
As long as it has a non-zero velocity, it will have a non-zero momentum.
A feather with no on it maintains constant velocity?
A feather with no momentum maintains constant velocity. Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity.
How do you find Mass using Momentum and velocity?
Momentum of a moving body is got by the product of the mass and velocity. Hence P = m v Momentum is a vector quantity Its unit in SI system is kg m s-1
How can momentum be increase of the body?
momentum of a body can be increased either by increasing velocity or by mass.since momentum = mass * velocity.
How can the momentum of a body be increase?
momentum of a body can be increased either by increasing velocity or by mass.since momentum = mass * velocity.
What is a property of momentum?
Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity. It is a conserved quantity and within an isolated system the total momentum is constant.
How a body can have angular momentum when it is moving in straight line?
If a body is moving in a straight line then it would have angular momentum about any point which is not along its line of motion. The magnitude of the angular momentum would be its velocity times the perpendicular distance between the line of motion and the point.
What effect does mass of the object have on its momentum?
Yes, mass will affect momentum in a collision or in anything else. Any object with mass and non-zero velocity will have momentum. Mass is directly proportional to momentum. Double the mass of an object moving with a given velocity and the momentum doubles.
If you are at rest do you have momentum?
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
Why does velocity stay constant with decreasing momentum?
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.
Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?
Angular momentum about the axis of rotation is the moment of linear momentum about the axis. Linear momentum is mv ie product of mass and linear velocity. To get the moment of momentum we multiply mv by r, r the radius vector ie the distance right from the point to the momentum vector. So angular momentum = mv x r But we know v = rw, so angular momentum L = mr2 x w (w-angular velocity) mr2 is nothing but the moment of inertia of the moving body about the axis of rotation. Hence L = I w.
