Is numerical ratio of average velocity to average speed always equal?
No, the numerical ratio of average velocity to average speed is not always equal. Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude. The ratio will be equal only when the object moves in a straight line.
What is the numerical ratio of a velocity to speed of an object?
Velocity is an object's Speed + Direction. For example, a cannon ball fired up at 45o to the ground may have a speed of 1000 ft/sec. However, its forward Velocity is:(1000 ft/sec) x (Sine 45o) = (1000 ft/sec) x (.707)= 707 ft/secSo, the ratio of the horizontal Velocity to the instantaneous Speed of the object is the SINE value of the angle of motion relative to the Horizontal axis.But you have to remember that there is a Vertical component of the object's Speed as well. In this case, the ratio is the COSINE 45o , which happens to be .707 as well. So the ball is going forward at 707 ft/sec, and upward at 707 ft/sec. at the same time.
Is numerical ratio of average velocity and average speed is always less than one?
No - the ratio can be exactly one if the velocity vector is always in the positive direction, i.e. motion is only in one direction and that is the direction designated as positive. If you designate the ratio by the symbol "r" the range of possible values is: -1 ≤ r ≤ 1
What is included in velocity that is not included in speed?
Velocity includes the direction of motion in addition to the numerical value of speed. This means that velocity specifies both how fast an object is moving and in which direction it is moving.
What quantity gives both the speed and the direction of an object?
Velocity represents a quantity that combines speed (magnitude) and direction for an object in motion. It is a vector quantity that includes both a numerical value for the speed and information about the direction of motion.
What is the numerical ratio of velocity of speed of an object?
The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.
Is numerical ratio of average velocity to average speed always equal?

Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude.

The speed of an object and the direction of its motion?
the object's 'velocity'
What is a vector of speed?
A vector of speed specifies the magnitude and direction of an object's velocity. It includes both the numerical value of speed (e.g. 50 km/h) and the direction the object is moving in (e.g. north).
Why is velocity a vector but not a speed?
Because velocity has a direction but speed does not. A vector has both a numerical value and a direction but a speed has only a numerical value and therefore it can't be represented by a vector.
What describes the direction and speed of an object?
Velocity describes the speed and direction of an object.velocityvelocity
What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
What is the specific direction of a speed of an object?
The specific direction of an object's speed is known as velocity. Velocity includes both the speed of the object and the direction in which it is moving.
