What is the definition of velocity?
Velocity is a measure of the speed of an object that is moving in a specific direction.Imagine walking across the room. If you walk in the same direction and do not change speed, your velocity remains constant until you stop moving. If you keep a constant speed, but change direction while walking, your velocity changes. If you walk in the same direction but slow down and speed up while walking, your velocity changes. Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.In common language, velocity is often used imprecisely to mean "speed".
Do velocity and acceleration of an object have to be in the same direction?
Yes because velocity vector is got by the product of acceleration vector and time which is scalar. v = a t (Except when you toss a ball upward, and until it reaches the top, it has upward velocity and downward acceleration. But in all other situations except for that one.) (And except when a yo-yo or an artificial satellite is moving in a circle, and its velocity is always tangent to the circle but its acceleration is always toward the center of the circle. But definitely in all other situations except for that one.)
Units of measure for velocity?
Velocity is measured as a unit of distance over time as in miles/hour (miles per hour). feet/second, kilometers/hour. It is the same as a measurement of speed except that there is also a direction component as in north or southwest. If you change the direction travel but maintain the same speed, it is still a change in velocity even though it is not a change in speed..
What quantity describes how quickly you change your speed?
acctually, you are describing two very similar quantities. th quantity that describes how quickly you change your speed, or how fast you are going is your acceleration, measured in distance per unit of time squared. the quantity that describes how quickly you change your direction is called velocity and it is identical to speed except in the fact that velocityshows how fast you go in a certain direction, or how quickly you change your direction
Which out of acceleration age speed temperature and velocity are vector quantities?
Acceleration and velocity are vector quantities because they have both magnitude and direction. Speed and temperature are scalar quantities because they only have magnitude.
How do you describe the quality quantity and symbol of these propositions and why nothing in this world is permanent except change all things in this world are impermanent except change?
it contain for element : the quantifier (Q) the subject term (S) the predicate term (P) and the coopering (c)

What factor is the difference between speed and velocity?
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE

How is speed acceleration and velocity the same?
Speed is the rate of change of position per unit time. The dimension is Length / Time. Common units are meters per second, miles per hour, feet per second. Velocity is nearly the same (same dimensions), except that velocity is a vector, meaning that it has direction as well.Now acceleration is the rate of change of velocity. It also is a vector. Its dimensions are Length/(time^2). Typical units are meters/sec^2 and feet/sec^2.
What are RCs responsible for?
rcs are responsible for the fooliwng actions except
Redo the problem worked out in the second column of page 128 of your textbook keep everything the same except change the braking time from 1.5 to 2 seconds what is the final velocity?
The answer is A. 10m/s *:)
How do units for speed and velocity compare?
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
