If a scooter has a mass of 20 kg and a velocity of 18 ms north what is the magnitude of its momentum?
360 kg/ms
If a scooter has a mass of 20 kg and a velocity of 18 m's north what is the magnitude of its momentum?
Momentum = m V = 20 x 18 = 360 kgm-meters
How does momentum work?
Momentum is the product of the mass and velocity of an object. Momentum= Mass x Velocity. When the object weighs 20kg and is traveling at 20m/s North it will have a momentum of 400kgm/s North.
What is magnitude - like in a vector?
Here's a vector: "30 miles an hour, going north"The name of that vector is "velocity". It has a magnitude and a direction. Themagnitude of this velocity is 30 miles an hour. We usually call that "speed".The direction of this velocity is "north".The magnitude tells how big the vector is. The direction tells which way it points."30 miles an hour" is not a velocity. It's a speed. Speed is only the magnitude ofa velocity vector, because it has no direction. Once we know the direction, we canput it together with the magnitude, and we'll have a vector, called "velocity".
Is the momentum of the car travelling north different from the one of the same car when it travels south at the same speed?
Momentum is a vector. This means it has magnitude and direction. The magnitude will be the same. But the sign will be different. If north is positive, south will be negative. This is the only difference.

When you say that a race car travels north at 100km per hour are you talking about velocity?
Yes. Velocity is a vector and therefore requires magnitude and direction: Magnitude: 100 kph Direction: North

What two pieces of information do vectors tell us?
A vector includes information about a magnitude, and a direction. For example, a velocity of "30 km/hour, towards the north-west".A vector includes information about a magnitude, and a direction.

Can two object's have same speed but different velocity?
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
What is the difference between speed and velocity in science?
Speed s a vector quantity, that is, it has magnitude (size) but no direction eg. 20km/h. Velocity is a vector quantity. It has both magnitude and direction eg. 50km/h north.
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.
In physics what is a vector?
A vector is the mathematical representation of an action or other entity that has both magnitude and direction. One of the most common contrasts is that between speed, which has magnitude but not direction, and velocity, which also has direction. A speed of 60 mph has the same meaning in any direction, but a velocity of 60 mph north has significantly different consequences from a velocity of 60 mph south, especially if one begins from some point on the north shore of a lake!
