Is momentum a vector quantity because it includes velocity which is also a vector quantity?
yes, momentum is a vector quantity.
' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
Which is 20 miles per hour north an example of?
A vector. This is because the quantity given has a magnitude (20mph) and a direction (North). It is also an example of a velocity.
How do you scale a quantity?
i think you mean a scaler quantity. a scaler quantity is something that is measured without a directional component to it. ie. mass, temperature, speed it could be negative value but the negative means its value. you can use a scale to measure scaler quantity. then there is vector quantities which have a direction to it. ie. velocity because something like velocity is 10m/s east OR -10m/s here the negative it is not a value but a direction (if 10m/s is to the right then -10m/s is to the left) don't confuse this with speed because speed is scaler it is just magnitude or value only. velocity is the displacement over time so it have a direction aswell. hope this helps
If the mass of a cart full of groceries decreases to half and its speed doubles does the momentum double or quadruple?
The answer to the question is " no ", because neither of the permitted choices is correct.Momentum = m V (mass times velocity)There are no squares in that formula. Momentum is directly proportional to both mass and speed.If mass is multiplied by 1/2 and speed is multiplied by 2, then the momentum is multiplied by(1/2) x (2) = 1The momentum doesn't change.
Is momentum a vector quantity because it includes velocity which is also a vector quantity?
yes, momentum is a vector quantity.
Is momentum a vector quantity?
Yes momentum is a vector quantity. Because p = m v. As m is scalar and v is vector then p the momentum has to be a vector. Here m is mass and v is velocity
What does change in momentum mean?
It means that the momentum increases, decreases, or simply changes its direction. The latter is because momentum is a vector quantity (that is, the direction is relevant). Momentum is defined as the product of velocity and mass.
Is momentum a vector?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
When a car increases its velocity its momentum?
When something increases in velocity, its momentum would increase because momentum is equal to its mass * velocity. This means that the momentum and velocity are proportional, so twice the velocity is twice the momentum, and so on.
Is it true that momentum is not equal to the mass of an object divided by its velocity?
That is true because momentum is mass times velocity
Why angular velocity is vector quantity?
Because it's a type of velocity and velocity is vector quantity
How does a bullet fired from a gun have ahigh momentum?
Momentum = mass x velocity A bullet has a high momentum because its velocity is really high.
How much momentum does an object have that is not moving?
If an object is at rest, it has no momentum because the formula for momentum is p = mv, where p= momentum, m = mass and v = velocity. If the object is at rest, then the velocity is zero, so p = m*0. therefore p = 0.
If two objects have the same velocity do they have the same momentum?
No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)
Why an object will move if its velocity is constant?
Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
Why momentum is the product of mass and velocity?
It's defined that way.
