If Momentum is a vector quantity because it includes velocity which is also a vector quantity?
= TRUE!
' 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.

= TRUE!
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is momentum a vector quantity?
Yes, momentum is a vector quantity because it has both magnitude and direction. It is defined as the product of an object's mass and its velocity, and the direction of momentum is the same as the direction of the object's velocity.
Is momentum a vector?
Yes, momentum is a vector quantity because it has both magnitude and direction. Momentum is calculated as the product of an object's mass and its velocity, and the direction of momentum is the same as the direction of the object's velocity.
Why momentum is the product of mass and velocity?
Momentum is the product of mass and velocity because it represents the quantity of motion an object has. A moving object with more mass or a higher velocity will have a greater momentum, reflecting the object's inertia and speed combined. Mathematically, momentum is calculated as momentum = mass x velocity.
Is linear momentum scalar quantity?
No, linear momentum is a vector quantity because it has both magnitude and direction. It is determined by the product of an object's mass and its velocity in a given direction.
Is direction a factor of calculating momentum?
Yes, direction is a factor in calculating momentum because momentum is a vector quantity that includes both magnitude and direction. The direction of an object's momentum is determined by the direction of its velocity.
Why does momentum have a direction?
Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the velocity of an object. This is because momentum is defined as the product of an object's mass and velocity, and velocity has a direction.
Why two objects move in opposite direction one will have positive momentum and other negative momentum?
When two objects move in opposite directions, their momenta have opposite signs because momentum is a vector quantity. One object will have positive momentum in the direction it is moving, while the other will have negative momentum in the opposite direction. This is due to the conservation of momentum, which states that the total momentum of a closed system remains constant.
How would momentum be considered a vector?
Momentum is a vector quantity because it has both magnitude and direction. In physics, momentum is defined as the product of an object's mass and its velocity, and its direction is always the same as the direction of the velocity of the object. As a result, momentum is treated as a vector with both magnitude (the amount of momentum) and direction.
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.
Which is a vector quantity speed or velocity?
Velocity is a vector quantity because it includes both the speed of an object and its direction of motion. Speed is a scalar quantity because it only represents the magnitude of motion without direction.
