Is km s a vector quantity?
No, km/s is not a vector quantity. It is a scalar quantity that represents speed, which describes how fast an object is moving without specifying its direction.
Is 68 km south a vector quantity or a scalar quantity?
The distance of 68 km south is a scalar quantity because it only has magnitude (68 km) and does not have direction. If it had both magnitude and direction, it would be a vector quantity.
What is an example for vector and scalar quantity?
An example of a vector quantity is velocity because it has both magnitude (speed) and direction (e.g., 50 km/h North). An example of a scalar quantity is temperature because it only has magnitude (e.g., 25 degrees Celsius).
What is velocity how is it different from speed?
Velocity is a vector quantity that includes both the speed of an object and its direction of motion. Speed, on the other hand, is a scalar quantity that only represents how fast an object is moving without considering the direction. Velocity provides a more comprehensive description of an object's motion compared to speed.
Define the term velocity. what are its various units Is it a scalar or vector quantity?
Velocity is the rate of change of an object's position in a specific direction. Its units include meters per second (m/s), kilometers per hour (km/h), and feet per second (ft/s). Velocity is a vector quantity as it has both magnitude (speed) and direction.
Is km s a vector quantity?
No, km/s is not a vector quantity. It is a scalar quantity that represents speed, which describes how fast an object is moving without specifying its direction.
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.

Is 68 km south a vector quantity or a scalar quantity?
The distance of 68 km south is a scalar quantity because it only has magnitude (68 km) and does not have direction. If it had both magnitude and direction, it would be a vector quantity.
How fast is 30 km per hour in miles per hour?
30 km/hour = 18.6 MPH.
How many miles per hour is 30 km per hour?
30 km per hour is equivalent to approximately 18.64 miles per hour.
What is the average speed of a car that travels 30 km in ½ hour?
60 km an hour

How long does it take a car to travel 30 km at 60km per hour?
Time = Distance/Speed = 30 km/60km per hour = 1/2 hour or 30 minutes
Are speed and distance a pair of vector quantities?
No, speed and distance are not a pair of vector quantities. Speed is a scalar quantity that represents how fast an object is moving regardless of direction, while distance is a scalar quantity that represents the total path length traveled. Vector quantities have both magnitude and direction.
What are some examples of scalar and vector quantities?
Scalar QuantitiesMost of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy.Vector QuantitiesA vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis, as shown in Figure 1. Using north/south and east/west reference axes, vector "A" is oriented in the NE quadrant with a direction of 45 north of the o EW axis. G iving direction to scalar "A" makes it a vector. The length of "A" is representative of its magnitude or displacement.Another AnswerA scalar quantity refers only to the magnitude of the quantity and answers the question how much. Ex. height, weight, volume, and the like. 2 lbs of sugar is scalar, 4 m long is scalarA vector quantity refers to both magnitude and direction and answers how much and where is it going, (in that sense)Ex. forces, velocity. 200 km/hr at N30degE is a vector, the force required to push a drum up or down a ramp is a vector, the force exerted by the cue stick in billiards is a vector a scalar is a number, like a distance... like the moon is 300.000km away from earth.a vector is a number AND a direction. It's like "moving east at 100km/h"while "moving at 100km/h" alone is a scalar.The idea is that a scalar has only ONE dimension, while a vector has several.
